'''Myriad 1 MA1101''' was a vision processing [[accelerator]] designed by [[Movidius]] and introduced in [[2010]] 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 ==
[[File:ma1101 multimedia.png|right|thumb|Multimedia]]
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]] {{sparc|V8}} [[LEON3]] core which is used for management and control and eight {{movidius|SHAVE v2.0|l=arch}} 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.
