Fair Value Disclosures [Text Block]	3. Fair values of assets and liabilities Determination of fair value Our cash equivalents and marketable securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The types of marketable securities valued based on quoted market prices in active markets include most U.S. government and agency securities, sovereign government obligations, money market securities and certain corporate obligations with high credit ratings and an ongoing trading market. The tables below present the balances of our assets and liabilities measured at fair value on a recurring basis as of April 30, 2016 and January 30, 2016 (in thousands): April 30, 2016 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Corporate bonds $ 7,040 $ 7,040 $ - $ - Fixed income mutual funds 1,302 1,302 - - Money market funds 109 109 - - Total cash equivalents and marketable securities 8,451 8,451 - - Restricted cash 823 823 - - Total assets measured at fair value $ 9,274 $ 9,274 $ - $ - January 30, 2016 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Corporate bonds $ 7,045 $ 7,045 $ - $ - Fixed income mutual funds 1,287 1,287 - - Money market funds 88 88 - - Total cash equivalents and marketable securities 8,420 8,420 - - Restricted cash 900 900 - - Total assets measured at fair value $ 9,320 $ 9,320 $ - $ - Assets measured and recorded at fair value on a non-recurring basis Our non-marketable preferred stock investments in privately-held venture capital funded technology companies are recorded at cost and are adjusted to fair value only in the event that they become other-than-temporarily impaired. As of April 30, 2016, we held equity investments in two privately-held venture capital funded technology companies and an equity investment in one joint venture, with an aggregate carrying value of $2.6 million. During the three months ending April 30, 2016, we recorded an impairment charge of $0.3 million in connection with one of our privately-held investments as we concluded the impairment to be other-than-temporary. We did not identify any other events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments during the three months ended April 30, 2016 and May 2, 2015. Each of these equity investments in privately-held companies constituted less than a 20% ownership position. Furthermore, we do not believe that we have the ability to exert significant influence over any of these companies.

In the fourth quarter of fiscal 2010, we purchased additional shares of preferred stock in Issuer A at a cost of $1.0 million. In November 2010, we loaned $1.0 million to Issuer A and received a secured promissory note. During the second quarter of fiscal 2015, the remaining balance of the note receivable from Issuer A was fully repaid. In the third quarter of fiscal 2011, we purchased shares of preferred stock in another privately-held technology company (“Issuer B”) at a total investment cost of $1.0 million. In the fourth quarter of fiscal 2016 and the first quarter of fiscal 2017, we recorded impairment charges each of $0.3 million on this investment as we concluded the impairment to be other-than-temporary. In the third quarter of fiscal 2012, we made an equity investment of $0.1 million in a privately-held joint venture (“Issuer C”). We made the above-described investments because we viewed the issuer as either having strategic technology or a business that would complement our technological capabilities or help create an opportunity for us to sell our chipset solutions. We analyze each investment quarterly for evidence of impairment. Our President and Chief Executive Officer is a member of the Board of Directors of both Issuer A and Issuer B. In the case of Issuer B, the investment transaction was negotiated without the personal involvement of the executive officer who had a personal interest in the transaction.

Business Combination Disclosure [Text Block]	6. Business combinations During the fourth quarter of fiscal 2016, we completed the acquisition of Bretelon, Inc. (“Bretelon”), which is engaged in developing an advanced form of mobile IoT technology (“Acquisition”). In accordance with the related We believe that our acquisition of Bretelon assists us in expanding our overall IoT offering. This Acquisition should expand our total addressable market to include outdoor applications, which we believe will complement our Z-Wave product line which currently covers primarily indoor applications. Additionally, we intend to take advantage of the synergy between these two product lines to service smart city and commercial opportunities that make outdoor use of the Z-Wave mesh network and mobile IoT connectivity. Certain members of our board of directors held an interest in Bretelon prior to the consummation of the Acquisition. For further discussion, refer to Note 16, “Related parties” of the consolidated financial statements included in our fiscal 2016 Annual Report on Form 10-K, as filed with the SEC on April 4, 2016 . The operations of Bretelon are included in our condensed consolidated financial statements from the date of Acquisition, which, during the first quarter of fiscal 2017, contributed approximately $0.2 million to our net loss in the accompanying condensed consolidated statement of operations. We recognized the Bretelon assets acquired and the liabilities assumed based upon their fair value measured as of the date of the Acquisition. The aggregate purchase price for Bretelon has been allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of Acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and is allocated to goodwill, none of which is expected to be tax deductible. Refer to Note 7, “Business combinations” of the consolidated financial statements included in our fiscal 2016 Annual Report on Form 10-K, as filed with the SEC on April 4, 2016 for the allocation of purchase price which is expected to be finalized within 12 months from the effective date of the acquisition . The following unaudited pro forma condensed consolidated results of operations give effect to the acquisition of Bretelon as if it had occurred as of the beginning of the fiscal period presented. The unaudited pro forma condensed consolidated results of operations are provided for informational purposes only and do not purport to represent actual consolidated results of operations had the acquisition occurred on the date assumed, nor are these financial statements necessarily indicative of future consolidated results of operations. We expect to incur costs and realize benefits associated with integrating the operations of the Bretelon business. The results of operations of the Bretelon business have been included in the condensed consolidated results of operations from November 4, 2015 inception to date. The unaudited pro forma consolidated results of operations do not reflect the cost of any integration activities or any benefits that may result from operating efficiencies or revenue synergies (in thousands, except per share data).

Commitments and Contingencies Disclosure [Text Block]	8. Commitments and contingencies Commitments Purchase commitments We place non-cancelable orders to purchase semiconductor products from our suppliers on an eight to twelve week lead-time basis. As of April 30, 2016, the total amount of outstanding non-cancelable purchase orders was approximately $29.0 million. Third-party licensed technology In October 2015, we entered into an agreement with a vendor to purchase $6.1 million of licensed technology for integration into future iterations of our products. Payments under this agreement are being made on an annual basis from December 2015 through December 2018. As of April 30, 2016, remaining payments under this agreement totaled $4.5 million. In addition to this agreement, we have entered into other purchase arrangements for certain licensed technology; remaining payments under these agreements totaled $5.1 million as of April 30, 2016. Payments under these arrangements are being made through fiscal 2018. We have fully accrued these amounts as of April 30, 2016. Design Tools We have entered into purchase arrangements with various vendors for certain design tools; remaining payments under these agreements totaled $1.6 million as of April 30, 2016. Payments under these arrangements are being made through fiscal 2018. We have fully accrued these amounts as of April 30, 2016. Royalties We pay royalties for the right to sell certain products under various license agreements. During the three months ended April 30, 2016 and May 2, 2015, we recorded gross royalty expense of $1.3 million and $0.8 million, respectively, in cost of revenue in the condensed consolidated statements of operations. Our wholly owned subsidiary, Sigma Designs Israel SDI Ltd. (formerly Coppergate Communications, Ltd.), participated in programs sponsored by the Office of the Chief Scientist of Israel's Ministry of Industry, Trade and Labor, or the OCS, for the support of research and development activities that we conducted in Israel. Through April 30, 2016, we had obtained grants from the OCS aggregating to $5.2 million of our research and development projects in Israel. We completed the most recent of these projects in 2013. We are obligated to pay royalties to the OCS, amounting up to 4.5% of the sales of certain products up to an amount equal to the grants received, plus LIBOR-based interest. As of April 30, 2016, our remaining potential obligation under these programs was approximately $1.1 million. Contingencies Product warranty In general, we sell products with a one-year limited warranty that our products will be free from defects in materials and workmanship. Warranty cost is estimated at the time revenue is recognized based on historical activity, and additionally, for any specific known product warranty issues. Accrued warranty cost includes hardware repair and/or replacement and is included in accrued liabilities in the accompanying condensed consolidated balance sheets. Details of the change in accrued warranty as of April 30, 2016 and May 2, 2015 are as follows (in thousands): Three Months Ended Balance Beginning of Period Additions and Adjustments Deductions Balance End of Period April 30, 2016 $ 959 $ 139 $ (138 ) $ 960 May 2, 2015 $ 864 $ 140 $ (143 ) $ 861 Litigation From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business. We expect that the number and significance of these matters will increase as our business expands. In particular, we could face an increasing number of patent and other intellectual property claims as the number of products and competitors in our industry grows. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources or cause us to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to us. If an unfavorable outcome were to occur against us, there exists the possibility of a material adverse impact on our financial position and results of operations for the period in which the unfavorable outcome occurs and, potentially, in future periods. As of April 30, 2016, we were not aware of any claims against us, asserted or otherwise. Indemnifications In certain limited circumstances, we have agreed and may agree in the future to indemnify certain customers against patent infringement claims from third parties related to our intellectual property. In these limited circumstances, the terms and conditions of sale generally limit the scope of the available remedies to a variety of industry-standard methods including, but not limited to, a right to control the defense or settlement of any claim, procure the right for continued usage, and a right to replace or modify the infringing products to render them non-infringing. To date, we have not incurred or accrued any significant costs related to any claims under such indemnification provisions. Our articles of incorporation and bylaws require that we indemnify our officers and directors against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to us. In addition, we have entered into separate indemnification agreements with each of our directors and executive officers, which provide for indemnification of these individuals under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in our charter documents and the form of indemnification agreement filed with our SEC reports. We purchase insurance to cover claims or a portion of the claims made against our directors and officers. Since a maximum obligation is not explicitly stated in our charter documents or in our indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, if any, the overall maximum amount of the obligations cannot be reasonably estimated. Third-party licensed technology We license technologies from various third parties and incorporate that technology into our products. Some of these licenses require us to pay royalties and others require us to report sales activities so that royalties may be collected from our customers. From time to time, we are audited by licensors of these technologies for compliance with the terms of these licenses. As of April 30, 2016, we are not aware of any audit by these licensors, intended or otherwise. We could be required to make additional payments as a result of pending or future compliance audits. For license agreements where we have royalty obligations, we charge any settlement payments that we make in connection with audits to cost of revenue. For license agreements where we simply have reporting obligations, we treat any settlement payments as penalties and charge the amounts to operating expenses in sales and marketing. We believe we are substantially in compliance with the terms of our licensing arrangements.

Earnings Per Share [Text Block]	9. Earnings per share Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the fiscal period. The weighted-average number of shares outstanding used in the computation of basic and diluted loss per share does not include the effect of the following potential outstanding shares of common stock. The effects of these potentially outstanding shares were not included in the calculation of basic and diluted loss per share because the effect would have been anti-dilutive (in thousands): Three Months Ended April 30 , 201 6 May 2 , 201 5 Stock options 2,388 2,963 Restricted stock units and awards 736 743

Under the 401(k) tax deferred savings plan, U.S. based employees may elect to reduce their current annual taxable compensation up to the statutorily prescribed limit, which is $18,000 in calendar year 2016. Employees age 50 or over may elect to contribute an additional $6,000. We made matching contributions to the 401(k) tax deferred savings plan during the three months ended April 30, 2016 of $0.2 million and made no matching contributions during the three months ended May 2, 2015. Endowment insurance pension plan Related to our acquisition of our DTV business in May 2012, we added operations in Shanghai, China. It is required by the “Procedures of Shanghai Municipality on Endowment Insurance for Town Employees” to provide pension insurance for Shanghai employees. The mandatory plan is managed by the local authority. Under the current plan, an employee will contribute 8.0% of the annual base to the plan and the employer will match 21% of the annual base. For calendar year 2015, the annual base is capped at RMB 16,353 per employee. We made matching contributions of $0.6 million and $0.5 million for the three months ended April 30, 2016 and May 2, 2015, respectively. Retirement pension plans We maintain retirement pension plans for the benefit of qualified employees in Denmark, Taiwan, the Netherlands, and Germany. We made matching contributions under these plans of $0.2 million for each of the three months ended April 30, 2016 and May 2, 2015. Severance plan We maintain a severance plan for several Israeli employees pursuant to Israel's Severance Pay Law based on the most recent salary of the employees multiplied by the number of years of employment. Upon termination of employment, employees are entitled to one month salary for each year of employment or a portion thereof. As of April 30, 2016, we have an accrued severance liability of $0.7 million fully offset by an asset of $0.7 million of severance employee funds. We made contributions of less than $0.1 million for each of the three months ended April 30, 2016 and May 2, 2015. Employee stock purchase plan During the first quarter of fiscal 2016, we discovered that we inadvertently sold shares of our common stock to our employees during fiscal 2015 in excess of the shares of common stock authorized to be issued under our 2010 Purchase Plan. As a result, we may have failed to comply with the registration or qualification requirements of the federal securities law. Certain purchasers of the shares that were issued in excess of the shares authorized under our 2010 ESPP may have the right to rescind their purchases from us for an amount equal to the purchase price paid for shares, plus interest from the date of purchase. These shares were treated as issued and outstanding for financial reporting purposes as of the original date of issuance. We intend to make a registered rescission offer in fiscal 2017 to eligible participants who purchased shares during the impacted offering periods in fiscal 2015. As of May 31, 2016, there were approximately 59,480 shares issued to participants in the 2010 ESPP during the impacted offering periods that continued to be held by the original purchasers of such shares which may be subject to the rescission rights referenced above. All of these shares were originally purchased for $3.89 per share. If holders of all these shares seek to rescind their purchases, we could be required to make aggregate payments of up to approximately $0.4 million based on initial estimates, which does not include statutory interest. However, the actual impact to our cash position may be lower depending on the number of holders who accept the rescission offer and tender their shares. Pursuant to the authoritative accounting guidance, the shares are considered mandatorily redeemable as the redemption may be outside of our control. We reclassified the aforementioned amount out of additional-paid-in-capital into accrued compensation and related benefits during fiscal 2015. We continue to carry the resulting liability on the accompanying condensed consolidated balance sheets as of April 30, 2016 and January 30, 2016 and will continue to do so until such rescission rights have expired subsequent to the aforementioned offering during fiscal 2017. We have not classified the shares themselves outside of permanent equity as these shares are legally outstanding with all rights and privileges therein. We also may be subject to civil and other penalties by regulatory authorities as a result of the failure to register these shares with the Securities and Exchange Commission. We do not believe that the failure to register the shares or the planned rescission offer will have a material impact on our condensed consolidated financial statements. We are also in the process of settling the potential tax consequences on behalf of our employees for issuing shares in excess of the number of shares reserved under our 2010 ESPP with relevant tax authorities. We may incur additional costs associated with any potential tax consequences and have included $0.4 million of expense associated with these additional costs which were recorded in accrued compensation and related benefits during fiscal 2015. We continue to carry the resulting liability on the accompanying condensed consolidated balance sheets as of April 30, 2016 and January 30, 2016 and will continue to do so until such settlement has been reached with the aforementioned authorities.

Income Tax Disclosure [Text Block]	11. Income taxes We recorded a provision for income taxes of $1.3 million and $2.5 million for the three months ended April 30, 2016 and May 2, 2015, respectively. The decrease in tax expense is primarily attributable to lower profitability in taxable jurisdictions in the first quarter of fiscal year 2017 as compared to the same period in fiscal year 2016 and changes in tax reserves. During the three months ended April 30, 2016 and May 2, 2015, we were unable to reasonably project our annual effective tax rate, and therefore computed our provision for income taxes based on year-to-date actual financial results. Included in our provision for income taxes are foreign exchange gains or losses on unsettled income tax liabilities.

Segment Reporting Disclosure [Text Block]	12. Segment and geographical information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance. We are organized as, and operate in, one reportable segment. Our operating segment consists of our geographically based entities in the United States, Israel and Singapore. Our chief operating decision-maker reviews consolidated financial information, accompanied by information about revenue by product group, target market and geographic region. We do not assess the performance of our geographic regions on other measures of income, expense or net income. Our net revenue is derived principally from the sales of integrated semiconductor solutions, which we sell across both of our target markets. Connected Smart TV Platforms consist of all products that are sold into digital televisions as well as other adjacent markets using chipset products that are designed for video post-processing, products delivering IP streaming video, including hybrid versions of these products, and communication devices that use a standard protocol to connect equipment inside the home and stream IP-based video and audio, VoIP, or data through wired or wireless connectivity. IoT Devices consist of all interconnected Z-Wave enabled gateways, appliances and devices that provide monitoring and control capabilities for the management of any consumer ecosystem. Our IoT Devices product line consists of our wireless Z-Wave chips, modules and Z-Wave mesh networking protocol. During the three months ended April 30, 2016, we derived a portion of our IoT Devices revenue from the achievement of a milestone under a development agreement in connection with our acquisition of Bretelon in the amount of $1.6 million. Our License and other markets include revenue derived from the licensing of our technology to third parties and other sources. Revenue derived from other sources includes software development kits, engineering support services for hardware and software, and engineering development for customization of chipsets and other accessories; revenue from this product group represented 0.4% and 0.5% of our total net revenue for the three months ended April 30, 2016 and May 2, 2015, respectively. Starting with the first quarter of fiscal 2017, we have combined certain previously reported target markets commensurate with changes taking effect in our industry as a whole. Specifically, we combined the Smart TV, Media Connectivity and Set-top Box markets into one target market, henceforth referred to as the Connected Smart TV Platforms target market. The aforementioned target market is intended to include all of our products sold into or supporting the digital television experience including products designed for video-post processing, delivering of IP streaming video, audio, VoIP, or data and the equipment intended to connect these various home entertainment products. We have historically and continue to operate under the belief that the Smart TV, Set-top Box and Media Connectivity products complement their respective value propositions to the markets into which we sell. This combination is intended to present this value proposition as a holistic solution or platform for the anticipated convergence of IP-video, audio and data delivery across any device within the connected home. All previously reported amounts in prior periods have been adjusted retrospectively to reflect our target market changes. Our IoT Devices market product categorizations remain unchanged, and beginning in the fourth quarter of fiscal 2016 includes amounts from our acquisition of Bretelon. The following tables set forth net revenue attributable to each target market (in thousands): Three Months Ended April 30, 2016 May 2, 2015 Connected Smart TV Platforms $ 43,247 $ 43,149 IoT Devices 10,337 12,457 License and other 191 306 Net revenue $ 53,775 $ 55,912 The following table sets forth net revenue for each geographic region based on the ship-to location of customers (in thousands): Three Months Ended April 30 , 201 6 May 2 , 201 5 Asia $ 46,041 $ 39,669 North America 6,615 12,153 Europe 1,119 2,765 Other Regions - 1,325 Net revenue $ 53,775 $ 55,912 The following table sets forth net revenue to each significant country based on the ship-to location of customers (in thousands): Three Months Ended April 30, 2016 May 2, 2015 China, including Hong Kong $ 27,457 $ 22,177 Taiwan 13,964 8,919 United States 6,589 12,146 Thailand 2,821 4,985 Rest of the world 2,944 7,685 Net revenue $ 53,775 $ 55,912 During the three months ended April 30, 2016, Sunjet Components Corporation and Silicon Application accounted for 22% and 11% of our net revenue, respectively.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation: We operate and report quarterly financial results that consist of 13 weeks and end on the last Saturday of the period. The first quarter of fiscal 2017 and fiscal 2016 ended on April 30, 2016 (91 days) and May 2, 2015 (91 days), respectively. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). They do not include all disclosures required by US GAAP for complete financial statements. Therefore, these financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto for the year ended January 30, 2016, included in our fiscal 2016 Annual Report on Form 10-K, as filed with the SEC on April 4, 2016, referred to as our fiscal 2016 Annual Report.
