Segment Reporting [Abstract] |
Segment Reporting | 15. Segment Reporting The Company operates as a single operating and reportable segment and derives substantially all of its revenue from development and sales of low-power AI-based processing and video and image processing SoC solutions. In determination of a reportable segment, the Company considers the research and development deployed, the nature of production process, the distribution channels of SoCs, as well as the Company’s management structure. The Chief Executive Officer of the Company has been identified as the Chief Operating Decision Maker (the CODM) and manages the Company’s operations as a whole. The CODM uses net loss presented on a consolidated basis to evaluate the financial performance and allocate resources. The CODM also monitors budget versus actual results of the operating segment. The measure of reportable segment assets is reported within the condensed consolidated balance sheets as total assets. The accounting policies for the measurement of net loss and total assets of the reportable segment have been described in the Note 1, Organization and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the 2025 fiscal year filed with the SEC on March 28, 2025.
