ADAS introduces depth perception

Depth perception can be added to advanced driver assistance systems (ADAS) says Light, as the company introduces its Clarity depth perception platform, based on Cadence’s Tensilica Vision Q7 DSP.

The next-generation ADAS provides long range, high resolution depth perception using industry standard cameras. The Tensilica Vision Q7 DSP provides real time data processing, ensuring low latency, high bandwidth transmission of high-resolution output, said the company.

Light says its ADAS enables machines to see better than humans by using two or more cameras, novel calibration and signal processing to provide “unprecedented depth quality across the camera’s field of view”. Integrating the Tensilica Vision Q7 DSP enables up to 10 times faster processing of measured depth compared to a quad-core CPU, improving real time accuracy and reliability, reported Light. The configurable and extensible Vision Q7 DSP is accompanied by optimised computer vision libraries, optional accelerators and toolchains that efficiently handle workloads. Light implemented its proprietary multi-view depth perception algorithms via custom instructions using the Tensilica Instruction Extension (TIE) language, which resulted in an additional four-fold performance improvement with three times the area / power savings, claimed Cadence.

Meeting functional safety requirements with full ISO 26262 compliance with ASIL-D is crucial in ADAS. The Tensilica Vision Q7 DSP certified IP is available with certified toolchains, libraries and a streamlined failure modes, effects and diagnostic analysis (FMEDA) flow.

“Light’s solution enables machines to see better than humans, and a key part of that is processing that information quickly enough to allow the machine to react to the world around it,” said Dave Grannan, CEO of Light. “Integrating the Cadence Tensilica Vision Q7 DSP provides us with enhanced signal processing capabilities at low power with low latency . . . helping us to provide accurate and reliable measured depth for future ADAS systems. Additionally, integrating ISO 26262-certified IP such as the Tensilica Vision Q7 DSP is critical when designing automotive-grade solutions,” he added.

Cadence applies its underlying Intelligent System Design strategy to deliver software, hardware and IP that turn design concepts into reality. Cadence customers deliver electronic products from chips to boards to systems for the most dynamic market applications, including consumer, hyperscale computing, 5G communications, automotive, mobile, aerospace, industrial and healthcare. 

Light is pioneering real-time 3D perception to redefine how vehicles see the world. The company’s breakthroughs in computational imaging with multi-camera calibration and advanced signal processing provide accurate depth at both near and far distances in real time.
