Fragrak or Streaming Hybrid Architecture Vector Engine v3.0 (SHAVE v3.0) is an accelerator microarchitecture designed by Movidius for their vision processors, serving as a successor to the SHAVE v2.0. SHAVE-based products are branded as the Myriad 2 family of vision processors.
History
The SHAVE v3.0 microarchitecture is based on the SHAVE v2.0 microarchitecture which Movidius disclosed in 2011. The architecture is a word of a 70-staff team consisting of 65 engineers - 10% working on hardware while the remaining 90% were working on the system tools and software design.
Process Technology
