Abstract

Myriad 2 is a multicore, always-on system on chip that supports computational imaging and visual awareness for mobile, wearable, and embedded applications. The vision processing unit incorporates parallelism, instruction set architecture, and microarchitectural features to provide highly sustainable performance efficiency across a range of computational-Imaging and computer vision applications, including those with low latency requirements on the order of milliseconds.
