Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1: DSP Group, Inc., a Delaware corporation, and its subsidiaries (collectively, the “Company”), are a fabless semiconductor company offering advanced chipset solutions for a variety of voice, audio, video and data applications. The Company is a worldwide leader in the short-range wireless communication market, enabling home and business networking convergence for voice, audio, video and data. The Company sells its products through distributors and directly to OEMs and original design manufacturers (ODMs) that incorporate the Company’s products into consumer and enterprise products. The Company expects that a limited number of customers, varying in identity from period-to-period, will account for a substantial portion of its revenues in any period. The loss of, or reduced demand for products from, any of the Company’s major customers could have a material adverse effect on the Company’s business, financial condition and results of operations. The following table represents the Company’s sales, as a percentage of the Company’s total revenues, for the years ended December 31, 2019, 2018 2017: Year ended December 31, Major Customers/ Distributors 201 9 201 8 201 7 VTech Holdings Ltd. 21 % 24 % 27 % Nexty Electronics Ltd.

While these foundries and test houses have been able to adequately meet the demands of the Company’s business, the Company is and will continue to be dependent upon these foundries and test houses to achieve acceptable manufacturing yields, quality levels and costs, and to allocate to the Company a sufficient portion of foundry and test capacity to meet the Company’s needs in a timely manner. Revenues could be materially and adversely affected should any of these foundries and test houses fail to meet the Company’s request for product manufacturing due to a shortage of production capacity, process difficulties, low yield rates or financial instability. Additionally, certain of the raw materials, components, and subassemblies included in the products manufactured by the Company’s original equipment manufacturer (OEM) customers, which incorporate the Company’s products, are obtained from a limited group of suppliers. Disruptions, shortages, or termination of certain of these sources of supply could occur and could negatively affect the Company’s financial condition and results of operations.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements are prepared according to United States generally accepted accounting principles (“U.S. GAAP”). a. Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. b. Financial statements in U.S. dollars: Most of the Company’s revenues are generated in U.S. dollars. In addition, a substantial portion of the Company’s costs are incurred in U.S. dollars. The Company’s management believes that the U.S. dollar is the currency of the primary economic environment in which the Company operates. Thus, the functional and reporting currency of the Company is the U.S. dollar. Monetary accounts maintained in currencies other than the U.S. dollar are remeasured into dollars in accordance with ASC No. 830 30, The financial statements of the Company’s subsidiary – DSP Group Technologies GmbH whose functional currency is in Euro, has been translated into dollars. All amounts on the balance sheets have been translated into the dollar using the exchange rates in effect on the relevant balance sheet dates. All amounts in the consolidated statements of operations have been translated into the dollar using the average exchange rate for the relevant periods. The resulting translation adjustments are reported as a component of accumulated other comprehensive income (loss) in changes in stockholders’ equity. Accumulated other comprehensive loss related to foreign currency translation adjustments, net amounted to $335 $327 December 31, 2019 2018, c. Principles of consolidation: The consolidated financial statements include the accounts of the Company. Intercompany transactions and balances have been eliminated in consolidation. d. Cash equivalents: Cash equivalents are short-term highly liquid investments, which are readily convertible to cash with original maturity of three e. Restricted deposits: Restricted deposits, which are deposits with original maturities of more than three one f. Short-term deposits: Bank deposits with original maturities of more than three one g. Marketable securities: The Company accounts for investments in debt securities in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 320 10, The Company classified all of its investments in marketable securities as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, reported in accumulated other comprehensive income (loss) using the specific identification method. The amortized cost of marketable securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in financial income, net. Interest and dividends on securities are included in financial income, net. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date and the entity’s expectations of sales and redemptions in the following year. The marketable securities are periodically reviewed for impairment. If management concludes that any of these investments are impaired, management determines whether such impairment is other-than-temporary. Factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value and the potential recovery period, and the Company’s intent to sell, or whether it is more likely than not not December 31, 2019, 2018 2017, not 3 h. Fair value of financial instruments: Cash and cash equivalents, restricted deposits, short-term deposits, trade receivables, trade payables and accrued liabilities approximate fair value due to short-term maturities of these instruments. Marketable securities and derivative instruments are carried at fair value. See Note 3 The Company accounts for certain assets and liabilities at fair value under ASC 820, The hierarchy below lists three one three Level 1 Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 Include other inputs that are directly or indirectly observable in the marketplace. Level 3 Unobservable inputs which are supported by little or no The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. i. Inventories: Inventories are stated at the lower of cost and net realizable value. Inventory reserves are provided to cover risks arising from slow-moving items or technological obsolescence. The Company and its subsidiaries periodically evaluate the quantities on hand relative to historical, current and projected sales volume. Based on this evaluation, an impairment charge is recorded when required to write-down inventory to its market value. Cost is determined as follows: Work in progress and finished products- on the basis of raw materials and manufacturing costs on an average basis. The Company regularly evaluates the ability to realize the value of inventory based on a combination of factors, including the following: historical usage rates and forecasted sales according to outstanding backlogs. Purchasing requirements and alternative usage are explored within these processes to mitigate inventory exposure. When recorded, the reserves are intended to reduce the carrying value of inventory to its net realizable value. Inventory of $7,464, $9,819 $9,422 December 31, 2019, 2018 2017, $382, $508 $468 may j. Property and equipment, net: Property and equipment are stated at cost, net of accumulated depreciation.

The computation of volatility uses a combination of historical volatility and implied volatility derived from the Company’s exchange traded options with similar characteristics. The risk-free interest rate assumption is based on U.S. treasury bill interest rates appropriate for the term of the Company’s employee equity-based awards. The dividend yield assumption is based on the Company’s historical and expectation of future dividend payouts and may The expected term of employee equity-based awards represents the weighted-average period the awards are expected to remain outstanding and is a derived output of the binomial model. The expected life of employee equity-based awards is impacted by all of the underlying assumptions used in the Company’s model. The binomial model assumes that employees’ exercise behavior is a function of the award’s remaining contractual life and the extent to which the award is in-the-money (i.e., the average stock price during the period is above the strike price of the award). The binomial model estimates the probability of exercise as a function of these two As equity-based compensation expense recognized in the consolidated statement of operations is based on awards ultimately expected to vest, it should be reduced for estimated forfeitures. The forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre and post-vesting forfeitures were estimated based on historical experience. The Company selected the Monte Carlo model as the most appropriate model for determining the fair value of its ESPP plan. The fair value for rights to purchase shares of common stock under the Company’s ESPP was estimated on each enrollment date using the risk-free interest rate and the share price for those dates. In addition, the expected life was assumed to be between six 24 27.75% 29.54% 2019, 29.6% 32.88% 2018 27.42% 34.92% 2017.

Use of Estimates, Policy [Policy Text Block]	a. Use of estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

[1]	Calculation of aggregate intrinsic value for options, RSUs and SARs outstanding and exercisable is based on the share price of the Company's common stock as of December 31, 2019, 2018 and 2017 which was $15.74, $11.20 and $12.50 per share, respectively. The intrinsic value for options and SARs exercised and RSUs vested during those years represents the difference between the fair market value of the Company's common stock on the date of exercise and vesting for RSUs and the exercise price of each option, RSU or SAR, as applicable.
[2]	Due to the ceiling imposed on the SAR grants, the outstanding amount above can be exercised for a maximum of 1,665 thousand shares of the Company's common stock as of December 31, 2019.
[3]	SAR grants made on or after January 1, 2012 are convertible for a maximum number of shares of the Company's common stock equal to 50% of the SAR units subject to the grant.
[4]	Due to the ceiling imposed on the SAR grants, the exercisable amount above can be exercised for a maximum of 561 thousand shares of the Company's common stock as of December 31, 2019.
