Tensilica Vision Q6 DSP to boost embedded vision and AI

April 12, 2018 // By Julien Happich
Cadence Design Systems has released its latest DSP for embedded vision and AI, the Tensilica Vision Q6 DSP built on a new and faster processor architecture.

The fifth-generation Vision Q6 DSP offers 1.5X greater vision and AI performance than its predecessor, the Vision P6 DSP, and 1.25X better power efficiency at the Vision P6 DSP's peak performance. The Vision Q6 DSP is targeted for embedded vision and on-device AI applications in the smartphone, surveillance camera, automotive, augmented reality (AR)/virtual reality (VR), drone and robotics markets.

A deeper, 13-stage processor pipeline and system architecture designed for use with large local memories enable the Vision Q6 DSP to achieve 1.5GHz peak frequency and 1GHz typical frequency at 16nm, in the same floorplan area as the Vision P6 DSP. As a result, designers using the Vision Q6 DSP can develop high-performance products that meet increasing vision and AI demands and power-efficiency needs.

An enhanced DSP instruction set results in up to 20 percent fewer cycles than the Vision P6 DSP for embedded vision applications/kernels such as Optical Flow, Transpose and warpAffine, and commonly used filters such as Median and Sobel. The new IP doubles system data bandwidth with separate master/slave AXI interfaces for data/instructions and multi-channel DMA to alleviate memory bandwidth challenges in vision and AI applications, also reducing latency and overhead associated with task switching and DMA setup.
