Tensilica P6 boosts image recognition performance for ADAS chip
Toshiba has picked the Tensilica Vision P6 DSP IP from Cadence for its next-generation automotive SoC to meet functional safety requirements. This Digital Signal Processor IP has been chosen for the combination of high compute throughput with low power consumption and small core area on the chip. Plus, it is certified to meet the functional safety requirements typical for automotive applications.

Offering up to 3.8X more power efficiency than CPUs alone and 1024 giga-operations (GOPS) of processing power, the Vision P6 DSP serves as offload engine, efficiently processing vision and AI workloads to meet the demands for accurate detection and identification of objects, Cadence advertises.

Besides compactness, performance and low power consumption, the Tensilica ecosystem was a deciding factor for Toshiba’s choice, said Cadence. The Japanese chipmaker has integrated the Cadence Xtensa Imaging Library (Xi-Lib) into its software development kit (SDK), enabling its customers to easily access the Vision P6 DSP to execute custom algorithms. Using the Xi-Lib enabled Toshiba to port their existing vision algorithms to run on the DSP, reducing development time and effort. In addition, the Vision P6 DSP core, development tools and libraries are all designed to enable SoC vendors to achieve ISO 26262 automotive safety integrity level D (ASIL D) certification.
