Advanced Matrix Extensions (AMX, also known as Intel® Advanced Matrix Extensions or Intel® AMX) is an extensions to the x86 instruction set architecture for microprocessors from Intel and AMD which is designed to work on matrices and is meant accelerate AI-related workload, was introduced by Intel in June 2020 and first supported by Intel with the Sapphire Rapids microarchitecture. It introduces 2-dimensional registers called "tiles" upon which accelerators can perform operations. It is intended as an extensible architecture, the first accelerator implemented is called TMUL (tile matrix multiply unit) [1] [2]
