It's a SLAM Dunk Programming the Vision Q7 DSP
April 20, 2020
The Tensilica Vision Q7 DSP is the sixth-generation vision and AI DSP. It has an enhanced instruction set and additional hardware for SLAM applications. Cadence has a SLAM library that is optimized for the Vision Q7 DSP and lets SLAM applications be coded quickly and efficiently. Let's take a quick look at the processor itself, and then look at the what SLAM is, and what functionality the SLAM library provides.
The Vision Q7 DSP hits a sweet spot in terms of performance and power. It is much higher performance than a general-purpose CPU, which lacks multiple SIMD lanes for parallel processing. GPUs typically have enough computational horsepower but they are very thermally costly, generating a lot of heat, and draining any batteries fast.
