DSP Boosts Depth-perception in Next-gen ADAS
Light Co. has leveraged Cadence’s innovative Vision DSP in it’s Clarity Depth Perception Platform, helping to provide accurate and reliable measured depth for future ADAS systems.
Depth-sensing and perception technology firm Light Co. has deployed the Tensilica Vision Q7 DSP from Cadence in it’s Clarity Depth Perception Platform, which provides long-range, high-resolution depth perception using industry-standard cameras benefiting advanced driver-assistance systems (ADAS). According to Cadence, integrating the Tensilica Vision Q7 DSP enables up to 10X faster processing of measured depth compared to a quad-core CPU, improving real-time accuracy and reliability. Additionally, the ISO 26262-certified IP such as the Tensilica Vision Q7 DSP is crucial when designing automotive-grade solutions.
The Tensilica Vision Q7 DSP is designed to provide Light with real-time data processing, ensuring low-latency, high-bandwidth transmission of high-resolution output.
Specifically designed to address the growing requirements of embedded vision and AI applications, the Vision Q7 DSP is accompanied by a wide range of optimized computer vision libraries, optional accelerators and toolchains that efficiently handle heavy workloads.
The press release also stated that Light implemented its proprietary multi-view depth perception algorithms using custom instructions of the Tensilica Instruction Extension (TIE) language. This has resulted in an additional 4X performance improvement with 3X area/power savings.
For ADAS, meeting functional safety requirements with full ISO 26262 compliance with ASIL-D is crucial. “The Tensilica Vision Q7 DSP’s availability as certified IP along with certified toolchains, libraries, and a streamlined failure modes, effects and diagnostic analysis (FMEDA) flow were key factors in Light’s selection of the Vision Q7 DSP”, the company noted.
