Advanced Matrix Extension (AMX) is an x86 extension that introduces an asynchronous accelerator framework for operating on matrices.

Overview

The Advanced Matrix Extension (AMX) is an x86 extension that introduces a new programming framework for working with matrices. AMX introduces two new components - a 2-dimensional register file called 'Tiles' and a set of accelerators that are able to operate on those tiles.
