ISO 26262 compliant safety design package for IP-based ADAS vision SoCs

January 05, 2016 // By Graham Prophet
DSP IP vendor CEVA has worked with Yogitech to advise on achieving ASIL B compliancy for the CEVA-XM4 imaging & vision DSP.

An ISO 26262 compliant safety design package helps engineers accelerate the certification of Advanced Driver Assistance Systems (ADAS) using the CEVA-XM4 imaging and vision DSP. Yogitech (Pisa, Italy), provider of functional safety solutions, was engaged by CEVA to deliver the Failure Modes Effects and Diagnostic Analysis (FMEDA) report and advise on achieving ASIL B compliancy. The CEVA-XM4 is already licensed and in design for safety-critical automotive applications and is the only licensable vision processor IP today to support ASIL B safety integrity level (in accordance with ISO 26262).

The CEVA-XM4 imaging and vision DSP is, the company asserts, suited to vision-based ADAS systems, offering processing power and energy efficiency for system designers to implement even the most complex algorithms for ADAS. The CEVA-XM4 is optimised for vision functions including auto emergency braking (AEB), free-space detection, traffic sign recognition, pedestrian detection and other neural network-based object detection and recognition applications. These automotive applications are critical for ADAS and autonomous driving systems and require ISO certification in order to ensure safe and reliable operation. With the release of the safety design package customers can accelerate the ASIL certification process for their CEVA-XM4 based designs, providing further cost efficiencies and lowering risk.

Eran Briman, vice president of marketing at CEVA, comments, “As the only vision processor IP today that can deliver ISO 26262 ASIL B compliance, both our existing and new CEVA-XM4 customers designing safety-critical ADAS systems will benefit from a significant time-to-market advantage.”
