Myriad 1 MA1101 was a vision processing accelerator designed by Movidius and introduced in 2009 designed to serve as an advanced real-time video editing accelerator for smartphones. The MA1101 is an identical variant of the MA1100 but had added compatibility for Android OS.

Overview

The MA1101 is a vision accelerator designed to work alongside a main host processors, typically in a mobile or embedded device. The chip itself independently communicates with the camera input and does the processing internally.

The MA1101 consists of a single SPARC V8 LEON3 core which is used for management and control and eight SHAVE v2.0 core which are the workhorse of this chip. Each core has 128 KiB of cache. The eight SHAVE cores together are capable of 20GFLOPS of processing power at just a few 100s milliwatt of power.
