Matrix Math eXtensions

(processor)(MMX) (NOT an acronym for "MultiMedia eXtension",according to Intel, but an Intel brand name) A set of 57 extrainstructions built into some versions of Intel's Pentiummicroprocessors for supporting SIMD operations onmultimedia and communications data types.

MMX-enhanced processors are due to be released early in 1997.They will be fully compatible with previous Intel processorsand software but software will only benefit if it is writtento use the new instructions. They can handle many commonmultimedia operations, such as digital signal processing,normally handled by a separate sound card or video card.
