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
- Main article: 28 nm lithography process
This microarchitecture was designed for TSMC's 28 nm process.
Architecture
Key changes from SHAVE v2.0
- 28 nm process (from 65 nm)
- 20-30x performance
- 600 MHz (3.33x, from 180 MHz)
- 12 SHAVE cores (from 8)
- 5x per-core performance improvement
- LEON4 SPARC core (from LEON3)
- Added support for OpenCL
Die
- TSMC's 28HPM process
- 27 mm² die size
