Organization Consolidation And Presentation Of Financial Statements [Abstract]	'
Organization and Basis of Presentation	'
	1. Organization and Basis of Presentation
	Organization
	Cavium, Inc., (the “Company”), was incorporated in the state of California on November 21, 2000 and was reincorporated in the state of Delaware effective February 6, 2007. The Company designs, develops and markets semiconductor processors for intelligent and secure networks.
	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Cavium, Inc., its wholly owned subsidiaries, and a variable interest entity, or VIE, of which the Company is the primary beneficiary. Under the accounting principles generally accepted in the United States of America, or US GAAP, a VIE is required to be consolidated by its primary beneficiary. The primary beneficiary is the party that absorbs a majority of the VIE’s anticipated losses and/or a majority of the expected returns. See Note 5 of Notes to Condensed Consolidated Financial Statements for detailed discussions of the VIE. All significant intercompany transactions and balances have been eliminated in consolidation.
	The condensed consolidated financial statements have been prepared in accordance with US GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by US GAAP for annual financial statements. For further information, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K (File No. 001-33435) on file with the SEC for the year ended December 31, 2013.
	The condensed consolidated financial statements contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to state fairly the Company’s condensed consolidated financial position at September 30, 2014, and the condensed consolidated results of its operations for the three and nine months ended September 30, 2014 and 2013, and condensed consolidated statements of cash flows for the nine months ended September 30, 2014 and 2013. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the full year.
	The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by US GAAP.
	Significant Accounting Policies
	The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. There had been no material changes to these accounting policies.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board, or FASB issued a new guidance on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The new revenue guidance’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the guidance requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods during the annual period. Early adoption is prohibited. Different transition methods are available - full retrospective method and a modified retrospective (cumulative effect) approach. The Company is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements.
	In June 2014, FASB issued an update to the accounting standards related to accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The update requires that a performance target in a share-based payment that affects vesting that could be achieved after the requisite service period should be accounted for as a performance condition under compensation-stock compensation guidance. As a result, the target is not reflected in the estimation of the award’s grant date fair value. Compensation cost would be recognized over the requisite service period, if it is probable that the performance condition will be achieved. The guidance is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods, with early adoption permitted. The Company is currently evaluating the effect of the adoption of this guidance on its financial statements.
	In August 2014, the FASB issued an update to the accounting standards related to management’s responsibility in evaluating whether there is substantial doubt about the company’s ability to continue as a going concern and on the related disclosures in the notes. The update requires management to evaluate, at each annual or interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. The guidance is effective for annual reporting periods ending after December 15, 2016 and for annual periods and interim periods thereafter, with early adoption permitted. The Company does not expect that this new change to the accounting guidance will have a significant impact on the Company’s consolidated financial statements.

	At September 30, 2014 and December 31, 2013, all of the Company’s investments were classified as cash equivalents and are comprised of an investment in a money market fund. In accordance with the guidance for fair value measurements and disclosures, the Company determined the fair value hierarchy of its money market fund as Level 1, which approximated $122.2 million and $94.2 million as of September 30, 2014 and December 31, 2013, respectively. The carrying amount of the Company’s accounts receivable, accounts payable and accrued expenses approximate fair value due to their short term maturities.
	The notes payable and other are carried at fair value and are a Level 3 measurement. See Note 5 of the Notes to Condensed Consolidated Financial Statements for further discussion of the fair value measurements.

	Variable Interest Entity
	Between May 2012 and September 2014, the Company entered into several note purchase agreements and promissory notes with Xpliant, Inc. (“Xpliant” or the “VIE”) to provide cash advances. Xpliant is a Delaware incorporated and privately held company, engaged in the design and development of next generation software defined network switch chips. The Company has concluded that it is the primary beneficiary of the VIE due to the Company’s involvement with the VIE and the purchase option to acquire the VIE. As such, the Company has included the accounts of the VIE in the condensed consolidated financial statements.
	As of September 30, 2014, the Company had made cash advances of $21.0 million, consisting of $10.0 million under nine convertible notes receivable which, as amended, matured on August 31, 2014 and $11.0 million under several promissory notes which mature between April 2015 and September 2015, or earlier at the closing date of acquisition. The outstanding convertible notes and promissory notes bear an annual interest rate of 6%. The Company had a purchase option to acquire the assets of the VIE on terms specified in one of the note purchase agreements. Two of the convertible notes held by the Company are collateralized by a lien on the VIE’s assets.
	In addition to the funding received by the VIE from the Company, between May 2012 and September 2014, certain third party investors (“non-controlling interest”) made cash advances of $13.0 million under fifteen convertible notes receivable which, as amended, matured on August 31, 2014. All of the convertible notes bear interest at a rate of 6%, payable at maturity. Two of the convertible notes held by a third party investor with a principal amount of $1.0 million matured and were paid by the VIE in December 2013. Pursuant to the convertible notes, in the event the VIE closes a corporate transaction, as defined in the convertible notes, the holders of the convertible notes will be entitled to receive two times the outstanding  principal plus any unpaid accrued interest, while in case of a qualified financing of the VIE, as defined in the convertible notes, the outstanding principal balance plus the accrued interest on the convertible notes will be automatically converted into convertible preferred stock of the VIE at a discounted price.
	In December 2013, a third party investor exchanged its convertible note with a principal of $1.4 million and invested additional cash of $1.5 million with the VIE for a $2.9 million convertible security which has the same features as the convertible notes, with the exception of the requirement for repayment, interest and maturity. The Company has determined that for accounting purposes, the convertible security has derivative features, and as such, the Company estimated the fair value of the derivative features based on market approach using Level 3 inputs. The assumptions used in the fair value estimate are related to the probability of the aforementioned capital scenarios. The assumptions used in the fair value estimate are based, in part, on significant uncertainties, are difficult to predict and could differ materially in the future. Based on the most reasonable assumptions determined by management, the fair value of the derivative feature of the convertible security at the issuance date was approximately the same as the principal amount. Accordingly, the Company classified the $2.9 million convertible security as a derivative liability within notes payable and other on the condensed consolidated balance sheets.
	All of the convertible notes and the derivative feature of convertible security relating to the non-controlling interests included in the condensed consolidated financial statements are classified as Level 3 liability due to the above mentioned features and therefore they are all measured and presented at fair value in the condensed consolidated financial statements.  The convertible notes and the derivative feature of the convertible security are remeasured at each reporting period and, depending on the probability of the occurrence of the features mentioned above, the valuation of these instruments could range from their current fair value to approximately two times the principal amount of the convertible notes and the convertible security. The probability scenarios used in the fair value estimation included assumptions of a corporate transaction and a qualified financing for both the convertible notes and derivative feature of convertible security and an additional probability assumption for a redemption at maturity for the convertible notes.
	On June 30, 2014, pursuant to the option to acquire the VIE set forth in one of the note purchase agreements, the Company provided notice to the VIE of its decision to exercise the purchase option. As a result, the occurrence of a corporate transaction is highly probable, which changed significantly the fair value estimation of the convertible notes and derivative feature of convertible security as of June 30, 2014 compared to the previous reporting periods. Considering the change in the probability of a corporate transaction, the estimated fair value of the convertible notes and derivative feature of the convertible security as of June 30, 2014 was close to two times the outstanding principal amount, factoring in the time value of money through settlement at maturity date. As a result, the Company recorded the change in fair value of the notes and other of $13.9 million in the statements of operations in the three months ended June 30, 2014. During the three months ended September 30, 2014, the Company recorded the change in fair value of the notes and other related to the time value of money. The change in estimated fair value recognized in the statements of operations for the three and nine months ended September 30, 2014 amounted to $0.1 million and $14.9 million, respectively.
	The table below summarizes the change in the value of the convertible notes and derivative features of the convertible security for the nine months ended September 30, 2014:
		Fair Value		Additions		Change in estimated fair value recognized in statements of operations		Fair Value
		As of December 31, 2013						As of September 30, 2014

	Total notes payable and other	$	13,512	$	1,400	$	14,888	$	29,800
	The significant components of the VIE’s financial statements included in the Company’s condensed consolidated financial statements as of September 30, 2014 include cash of $1.5 million; property and equipment and intangible assets of $9.7 million; accounts payable and accrued expenses of $2.9 million; notes payable and other of $29.8 million; capital lease and technology license obligations of $9.7 million and non-controlling interest of $21.8 million. As of December 31, 2013, the significant component of the VIE’s financial statements included in the Company’s condensed consolidated financial statements include cash of $1.9 million; property and equipment and intangible assets of $6.7 million; accounts payable and accrued expenses of $3.4 million; notes payable and other of $13.5 million; capital lease and technology license obligations of $6.3 million and non-controlling interest of $11.8 million. The Company’s portion of the net loss of the VIE for the three months ended September 30, 2014 and 2013 was $4.3 million and $1.3 million, respectively, and for the nine months ended September 30, 2014 and 2013 was $23.9 million and $4.1 million, respectively. Included in the net loss for the nine months ended September 30, 2014 was a charge of $14.9 million related to the change in fair value of notes payable and other.
	On July 30, 2014, the Company entered into an Agreement and Plan of Merger and Reorganization, which was amended on October 8, 2014 (the “Merger Agreement”) with the VIE. Under the terms of the Merger Agreement, the Company will pay approximately $3.6 million in total consideration in a mix of cash and shares of the Company’s common stock in exchange for all outstanding securities held by Xpliant stockholders. The transaction contemplated by the Merger Agreement is expected to be completed before April 15, 2015, subject to certain closing conditions. The Company will also provide additional funding to the VIE to pay-out its outstanding liabilities, expenses and other costs through the completion of the Merger Agreement.
	In addition, pursuant to the Merger Agreement and in connection with the transaction contemplated by the Merger Agreement, in October 2014, the Company extended additional loans to the VIE in the amount of $39.8 million in exchange for promissory notes that bear annual interest rate of 6% that mature in October 2015, or earlier of the closing date of the acquisition. In October 2014, these cash advances to the VIE were used settle all outstanding convertible notes, related accrued interest and convertible security held by non-controlling interest $30.8 million. Additionally, $1.7 million was used to make cash payments to the employees of the VIE and $7.3 million to cover settlement of certain outstanding liabilities of the VIE. Further, per the Merger Agreement, in October 2014, the Company issued RSU’s of approximately 193,000 shares with a fair value of $8.7 million based on the Company’s stock price at the actual grant date to the employees of the VIE.
	Disposition of Certain Consumer Product Assets
	In September 2012, the Company completed the sale of certain consumer product assets to a third party company. The consumer product assets that were sold originated from the acquisition of Star Semiconductor Corporation in fiscal year 2008 and had been further developed by the Company. Under an asset purchase agreement, the Company agreed to transfer certain assets such as property and equipment and intangible assets to the third party company for an aggregate cash consideration of $2.4 million, payable in installments starting from January 10, 2013 through January 10, 2015. The Company determined that the payment terms were not fixed and determinable and as such the Company treated this transaction as disposition of assets and will recognize the future payments as a credit to sales, general and administrative expenses when the payments are due. The carrying value of the assets related to the sale of $2.7 million was recognized as a loss on disposition of certain consumer product assets within sales, general and administrative expenses during the third quarter of 2012. The Company received total installment cash consideration of $0.3 million each for the three months ended September 30, 2014 and 2013, respectively and $0.8 million each for the nine months ended September 30, 2014 and 2013, respectively. The cash consideration received was recognized as credits within sales, general and administrative expenses.
	Sale of Held for Sale Assets
	In January 2013, the Company completed the sale of certain assets to a third-party company. The assets sold originated from the acquisition of MontaVista Software, Inc. in fiscal year 2009. Under the asset purchase agreement, the Company agreed to transfer certain assets for an aggregate cash consideration of $3.3 million and the carrying value of the assets held for sale was approximately $2.6 million. The difference between the sale consideration and the carrying value of the assets held for sale of $0.7 million was recognized as a gain on sale of held for sale assets within sales, general and administrative expenses during the first quarter of 2013.

	The following table summarizes the details related to stock options granted and outstanding under the 2007 Equity Incentive Plan and 2001 Stock Incentive Plan for the nine months ended September 30, 2014:
			Number of Shares Outstanding				Weighted Average Exercise Price
	Balance as of December 31, 2013			3,552,216			$	17.79
	Options granted			165,000				38.78
	Options exercised			(976,984	)			13.96
	Options cancelled and forfeited			(8,000	)			28.45
	Balance as of September 30, 2014			2,732,232				20.4
	No stock option was granted during the three months ended September 30, 2014 and September 30, 2013. The fair value of each option grant for the nine months ended September 30, 2014 and 2013 were estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions below.
			Three Months Ended September 30,							Nine Months Ended September 30,
			2014				2013			2014			2013
	Risk-free interest rate			-				-		1.26% to 1.47%			0.32% to 1.04%
	Expected life			-				-		3.77 to 4.53 years			3.77 to 4.53 years
	Dividend yield			-				-			0%			0%
	Volatility			-				-		43.76% to 45.05%			45.82% to 49.60%
	The estimated weighted-average grant date fair value of options granted for the nine months ended September 30, 2014 and 2013 was $14.63 per share and $14.91 per share, respectively.
	As of September 30, 2014, there is $5.1 million of unrecognized compensation costs, net of estimated forfeitures, related to stock options granted under the Company’s 2007 Equity Incentive Plan and 2001 Stock Incentive Plan. The unrecognized compensation cost is expected to be recognized over a weighted average period of 2.32 years.
	The following table summarizes the details related to restricted stock units, or RSUs, granted and outstanding under the 2007 Equity Incentive Plan for the nine months ended September 30, 2014:
			Number of Shares				Weighted-Average Grant Date Fair Value Per Share
	Balance as of December 31, 2013			1,776,170			$	35.64
	Granted			1,310,345				39.31
	Issued and released			(724,846	)			35.25
	Cancelled and forfeited			(106,272	)			36.61
	Balance as of September 30, 2014			2,255,397				37.86
	For RSUs, stock-based compensation expense is calculated based on the market price of the Company’s common stock on the date of grant, multiplied by the number of RSUs granted. The grant date fair value of RSUs, less estimated forfeitures, is recorded on a straight-line basis, over the vesting period.
	In February 2014, the Company granted one-year performance-based RSU’s. Based on the Company’s evaluation of the probability of achieving the milestone as of September 30, 2014, the Company determined that the fair value of these performance RSU’s was $2.7 million and recorded the related stock-based compensation expense for the three and nine months ended September 30, 2014. In May 2014, the Company granted a performance-based RSU. Based on the Company’s evaluation of the probability of achieving the milestones as of September 30, 2014, the Company determined that the fair value of this performance RSU was $1.5 million; however, no stock-based compensation expense recorded during three and nine months ended September 30, 2014 related to this performance RSU grant. The Company continues to evaluate the probability of achieving the milestones for each of the performance-based RSU grants at each reporting period and will update the RSU expense which is included in stock-based compensation expense.
	As of September 30, 2014, there was $66.1 million of unrecognized compensation costs, net of estimated forfeitures related to RSUs granted under the Company’s 2007 Equity Incentive Plan. The unrecognized compensation cost is expected to be recognized over a weighted average period of 2.56 years.

Income Taxes	'
	9. Income Taxes
	The quarterly provision for income taxes is based on the estimated annual effective tax rate, plus any discrete items. The Company updates its estimate of its annual effective tax rate at the end of each quarterly period. The estimate takes into account estimations of annual pre-tax income, the geographic mix of pre-tax income and interpretations of tax laws and the possible outcomes of current and future audits.
	The following table presents the provision for income taxes and the effective tax rates for the three and nine months ended September 30, 2014 and 2013:
		Three Months Ended September 30,						Nine Months Ended September 30,
		2014			2013			2014			2013
		(in thousands)						(in thousands)
	Income (loss) before income taxes	$	2,917		$	1,629		$	(11,975	)	$	(9,360	)
	Provision for income taxes		811			714			1,365			1,817
	Effective tax rate		27.8	%		43.8	%		(11.4	)%		(19.4	)%
	The provision for income taxes for the three and nine months ended September 30, 2014 was primarily related to earnings in foreign jurisdictions. The difference between the provision for or benefit from income taxes that would be derived by applying the statutory rate to the Company’s income (loss) before income taxes and the provision for income taxes recorded for the three and nine months ended September 30, 2014 was primarily attributable to the valuation allowance, the difference in foreign tax rates and an increase in the indefinite lived intangible related deferred tax liability. The provision for income taxes for the three and nine months ended September 30, 2013 was primarily related to earnings in foreign jurisdictions and additional establishment of unrecognized tax benefits in foreign jurisdictions. The difference between the provision for or benefit from income taxes that would be derived by applying the statutory rate to the Company’s income (loss) before income taxes and the provision for income taxes recorded for the three and nine months ended September 30, 2013 was primarily attributable to the impact of losses that are not benefited, the difference in foreign tax rates and an increase in indefinite lived intangible related deferred tax liability.
	The Company’s net deferred tax assets relate predominantly to its United States tax jurisdiction. The need for a valuation allowance requires an assessment of both positive and negative evidence when determining whether it is more-likely-than-not that deferred tax assets are recoverable; such assessment is required on a jurisdiction-by-jurisdiction basis. In making such assessment, significant weight is given to evidence that can be objectively verified. After considering both negative and positive evidence to assess the recoverability of the Company’s net deferred tax assets during the fourth quarter of 2012, the Company determined that it was more-likely-than-not it would not realize the full value of its federal and state deferred tax assets. As such, the Company determined that as of December 31, 2012, a full valuation allowance was required on its net federal and state deferred tax assets. Adjustments could be required in the future if the Company concludes that it is more-likely-than-not that these net deferred tax assets are recoverable. A release of the valuation allowance could have the effect of decreasing the income tax provision in the period the valuation allowance is released. The Company continues to monitor the likelihood that it will be able to recover its deferred tax assets. As of September 30, 2014, the Company believes that it is not more likely than not that it will be able to fully realize its United States federal and state deferred tax assets and, as such, the Company continues to provide a full valuation allowance on those deferred tax assets.
	As of September 30, 2014 and December 31, 2013, the Company had unrecognized tax benefits for income taxes associated with uncertain tax positions of $14.4 million and $14.6 million, respectively. If all of these unrecognized tax benefits were recognized, $0.7 million would reduce the Company’s effective tax rate. The Company is not anticipating any significant changes in unrecognized tax benefits in the next 12 months.
	The Company’s major tax jurisdictions are the United States federal government, the states of California and Massachusetts, Japan, India, China and Singapore. The Company files income tax returns in the United States federal jurisdiction, the states of California and Massachusetts, various other states, and foreign jurisdictions in which it has a subsidiary or branch operations. The United States federal corporation income tax returns beginning with the 2000 tax year remain subject to examination by the Internal Revenue Service, or IRS. The California corporation income tax returns beginning with the 2000 tax year remain subject to examination by the California Franchise Tax Board. As of September 30, 2014, there are no on-going tax audits in the major tax jurisdictions other than India and Singapore. The India tax audit is for the tax years 2010, 2011 and 2012, and the Singapore tax audit is for the tax year 2012. The Company does not expect any significant tax adjustments from either of these audits.
	The federal research and development credits regulation, which was extended for two years under The American Taxpayer Relief Act of 2012, expired at the end of 2013.  As a result, the 2014 quarterly provision and the annual effective tax rate did not consider the effects of the federal research and development credits.

	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Cavium, Inc., its wholly owned subsidiaries, and a variable interest entity, or VIE, of which the Company is the primary beneficiary. Under the accounting principles generally accepted in the United States of America, or US GAAP, a VIE is required to be consolidated by its primary beneficiary. The primary beneficiary is the party that absorbs a majority of the VIE’s anticipated losses and/or a majority of the expected returns. See Note 5 of Notes to Condensed Consolidated Financial Statements for detailed discussions of the VIE. All significant intercompany transactions and balances have been eliminated in consolidation.
	The condensed consolidated financial statements have been prepared in accordance with US GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by US GAAP for annual financial statements. For further information, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K (File No. 001-33435) on file with the SEC for the year ended December 31, 2013.
	The condensed consolidated financial statements contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to state fairly the Company’s condensed consolidated financial position at September 30, 2014, and the condensed consolidated results of its operations for the three and nine months ended September 30, 2014 and 2013, and condensed consolidated statements of cash flows for the nine months ended September 30, 2014 and 2013. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the full year.
	The condensed consolidated balance sheet at December 31, 2013 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by US GAAP.

	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board, or FASB issued a new guidance on the recognition of revenue from contracts with customers, which includes a single set of rules and criteria for revenue recognition to be used across all industries. The new revenue guidance’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the guidance requires five basic steps: identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when or as the entity satisfies a performance obligation. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods during the annual period. Early adoption is prohibited. Different transition methods are available - full retrospective method and a modified retrospective (cumulative effect) approach. The Company is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements.
	In June 2014, FASB issued an update to the accounting standards related to accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The update requires that a performance target in a share-based payment that affects vesting that could be achieved after the requisite service period should be accounted for as a performance condition under compensation-stock compensation guidance. As a result, the target is not reflected in the estimation of the award’s grant date fair value. Compensation cost would be recognized over the requisite service period, if it is probable that the performance condition will be achieved. The guidance is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods, with early adoption permitted. The Company is currently evaluating the effect of the adoption of this guidance on its financial statements.
	In August 2014, the FASB issued an update to the accounting standards related to management’s responsibility in evaluating whether there is substantial doubt about the company’s ability to continue as a going concern and on the related disclosures in the notes. The update requires management to evaluate, at each annual or interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. The guidance is effective for annual reporting periods ending after December 15, 2016 and for annual periods and interim periods thereafter, with early adoption permitted. The Company does not expect that this new change to the accounting guidance will have a significant impact on the Company’s consolidated financial statements.
