Intrinsics for Intel® Advanced Matrix Extensions (Intel(R) AMX) Instructions

Intel® Advanced Matrix Extensions (Intel® AMX) is a new 64-bit programming paradigm consisting of two components:

  • A set of 2-dimensional registers (tiles) representing sub-arrays from a larger 2-dimensional memory image

  • An accelerator that is able to operate on tiles; the first implementation of this accelerator is called TMUL (tile matrix multiply unit).

The following sections show intrinsics that are available for Intel(R) Advanced Matrix Extension Instructions.
