Organization and nature of operations: two Basis of presentation: November 2015, On January 23, 2018, February 3, 2018, On January 23, 2018 February 3, 2018, Accounting period: 52 53 January 31 February 3, 2018 53 2017 2016 January 28, 2017 January 30, 2016 52 Use of estimates in the preparation of consolidated financial statements: not may Restructuring charges March 24, 2017, 2018 2018 2018 Expenses recognized for restructuring activities impacting our operating expenses are included in “Restructuring costs” in the consolidated statements of operations. Accruals are recorded when management has approved a plan to restructure operations and a liability has been incurred. The restructuring accruals are based upon management estimates at the time they are recorded. These estimates can change depending upon changes in facts and circumstances subsequent to the date the original liability was recorded. During fiscal 2018, 2017 2016, $9.3 zero $0.1 Fair value of financial instruments: 820 three may Level 1 Level 2 1 not Level 3 no For certain of our assets and liabilities including cash and cash equivalents, accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these items. Marketable securities consist of available-for-sale securities that are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of shareholders’ equity. The fair value of cash equivalents and certain marketable securities is determined based on “Level 1” In accordance with the fair value accounting requirements, companies may not Cash and cash equivalents: 90 Short and long-term marketable securities 90 one one may The difference between amortized cost (cost adjusted for amortization of premiums and accretion of discounts, which is recognized as an adjustment to interest income) and fair value, representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income (loss) within shareholders’ equity. Any gains and losses on the sale of marketable securities are determined based on the specific identification method. We monitor all of our marketable securities for impairment and if these securities are reported to have a decline in fair value, we use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and future prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may No 2018, 2017 2016. no February 3, 2018. Accounts receivable and allowances: may In establishing the allowance for sales returns, we make estimates of potential future returns of products for which revenue has been recognized in the current period, including analyzing historical returns, current economic trends and changes in customer demand and acceptance of our products. Our allowance for sales returns, discounts and bad debt was $2.0 $1.6 February 3, 2018 January 28, 2017, may Inventory: first first not not We write-off inventory that is obsolete. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles. Provisions for excess and obsolete inventory are charged to cost of revenue. At the time of the loss recognition, a new and lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not Inventory write-downs inherently involve assumptions and judgments as to amount of future sales and selling prices. As a result of our inventory valuation reviews, we charged provisions for excess and obsolete inventory of approximately $4.9 $2.0 $3.2 2018, 2017 2016, $0.5 $0.3 $0.9 2018, 2017 2016, no not Warranty: one may Software, equipment and leasehold improvements: one five Business combinations: not may Intangible and other long-lived assets: two three Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired.

As of February 3, 2018, 9 We first not Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include forecasts of revenue and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, economic market conditions and a determination of appropriate market comparables and expected realizable value. We base our fair value estimates on assumptions we believe to be reasonable at that time, however, actual future results may We have relied on three third For the fiscal year ended February 3, 2018 not not 11 Impairment of goodwill: may not first not not two The first two second second For the fiscal year ended February 3, 2018 not 10 Long-term investments: 20% may not Revenue recognition: 97%, 97% 99% 2018, 2017, 2016, not 100% not 100% not no not 5 On occasion, we derive revenue from the license of our internally developed intellectual property (“IP”). IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Our license fee arrangements generally include multiple deliverables and we are required to determine whether there is more than one third not Our process for determining our ESP for deliverables without VSOE or TPE considers multiple factors that may may For deliverables related to licenses of our technology that involve significant engineering services, we recognize revenue in accordance with the provisions of the proportional performance method or milestone method, as applicable. We determine costs associated with engineering services using actual labor dollars incurred and estimate other direct or incremental costs allocated based on the percentage of time the engineer(s) spent on the project. These costs are deferred until revenue recognition criteria have been met, at which time they are reclassified as cost of revenue. Licensing revenue deliverables are generally recognized using the milestone method. Under the milestone method, we recognize revenue that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. To be considered substantive, the consideration earned by achieving the milestone should be (a) commensurate with either (i) the vendor’s performance to achieve the milestone or (ii) to the enhancement of the value of the item delivered as a result of a specific outcome resulting from the vendor’s performance to achieve the milestone (b) the consideration should relate solely to past performance, and (c) the consideration should be reasonable relative to all deliverables and payment terms in the arrangement.

Earnings Per Share [Text Block]	13 . Earnings per share Basic net (loss) income per share is computed by dividing net (loss) income by the weighted-average number of common shares outstanding for the fiscal period. Diluted net loss per share is the same as basic net loss per share as the inclusion of potentially issuable shares is anti-dilutive. Diluted net income per share is computed by adjusting outstanding shares and calculated using the treasury stock method for any dilutive effects of stock incentive awards. Under the treasury stock method, an increase in the fair market value of our common stock results in a greater dilutive effect from outstanding stock options, restricted stock units and stock purchase rights. Additionally, the exercise of employee stock options and stock purchase rights and the vesting of restricted stock units results in a further dilutive effect on net income per share.

Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring charges March 24, 2017, 2018 2018 2018 Expenses recognized for restructuring activities impacting our operating expenses are included in “Restructuring costs” in the consolidated statements of operations. Accruals are recorded when management has approved a plan to restructure operations and a liability has been incurred. The restructuring accruals are based upon management estimates at the time they are recorded. These estimates can change depending upon changes in facts and circumstances subsequent to the date the original liability was recorded. During fiscal 2018, 2017 2016, $9.3 zero $0.1
Fair Value Measurement, Policy [Policy Text Block]	Fair value of financial instruments: 820 three may Level 1 Level 2 1 not Level 3 no For certain of our assets and liabilities including cash and cash equivalents, accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these items. Marketable securities consist of available-for-sale securities that are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of shareholders’ equity. The fair value of cash equivalents and certain marketable securities is determined based on “Level 1” In accordance with the fair value accounting requirements, companies may not
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents: 90
Marketable Securities, Policy [Policy Text Block]	Short and long-term marketable securities 90 one one may The difference between amortized cost (cost adjusted for amortization of premiums and accretion of discounts, which is recognized as an adjustment to interest income) and fair value, representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income (loss) within shareholders’ equity. Any gains and losses on the sale of marketable securities are determined based on the specific identification method. We monitor all of our marketable securities for impairment and if these securities are reported to have a decline in fair value, we use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and future prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may No 2018, 2017 2016. no February 3, 2018.
Receivables, Policy [Policy Text Block]	Accounts receivable and allowances: may In establishing the allowance for sales returns, we make estimates of potential future returns of products for which revenue has been recognized in the current period, including analyzing historical returns, current economic trends and changes in customer demand and acceptance of our products. Our allowance for sales returns, discounts and bad debt was $2.0 $1.6 February 3, 2018 January 28, 2017, may
Inventory, Policy [Policy Text Block]	Inventory: first first not not We write-off inventory that is obsolete. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles. Provisions for excess and obsolete inventory are charged to cost of revenue. At the time of the loss recognition, a new and lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not Inventory write-downs inherently involve assumptions and judgments as to amount of future sales and selling prices. As a result of our inventory valuation reviews, we charged provisions for excess and obsolete inventory of approximately $4.9 $2.0 $3.2 2018, 2017 2016, $0.5 $0.3 $0.9 2018, 2017 2016, no not

Other intangible assets primarily represent purchased developed technology, customer relationships, purchased IP, non-compete agreements and trademarks. We currently amortize our intangible assets with definitive lives over periods ranging from three ten

As of February 3, 2018, 9 We first not Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include forecasts of revenue and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, economic market conditions and a determination of appropriate market comparables and expected realizable value.

IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Our license fee arrangements generally include multiple deliverables and we are required to determine whether there is more than one third not Our process for determining our ESP for deliverables without VSOE or TPE considers multiple factors that may may For deliverables related to licenses of our technology that involve significant engineering services, we recognize revenue in accordance with the provisions of the proportional performance method or milestone method, as applicable. We determine costs associated with engineering services using actual labor dollars incurred and estimate other direct or incremental costs allocated based on the percentage of time the engineer(s) spent on the project. These costs are deferred until revenue recognition criteria have been met, at which time they are reclassified as cost of revenue. Licensing revenue deliverables are generally recognized using the milestone method. Under the milestone method, we recognize revenue that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. To be considered substantive, the consideration earned by achieving the milestone should be (a) commensurate with either (i) the vendor’s performance to achieve the milestone or (ii) to the enhancement of the value of the item delivered as a result of a specific outcome resulting from the vendor’s performance to achieve the milestone (b) the consideration should relate solely to past performance, and (c) the consideration should be reasonable relative to all deliverables and payment terms in the arrangement.
