SABRE was a test microprocessor designed by Movidius for the acceleration of machine vision. The SABRE microprocessor eventually lead to the production definition of the Myriad 1 line of vision accelerators.

Overview

SABRE is capable of 20 GLOPS at low 100s mW of power through the use of 9 execution units consisting of a SPARC V8 LEON3 core and 8 additional SHAVE v2.0 cores.

The test platform consisted of a Samsung 6410 daughtercard which incoluded an S3C6410X processor (ARM11) and a Movidius MV0108 SABRE daughtercard which had the SABRE processor.
