MMX — An Overview MMX was the first set of SIMD extensions applied to Intel's 80x86 instruction set. It was introduced in 1997. MMX introduces a number of new instructions that operate on single 64-bit quantities, 2 32-bit quantities, 4 16-bit quantities, or 8 8-bit quantities all at once. Availability in the MMX instruction set does not ap-ply to 128-bit packed integer instructions, which require SSE2. Availability in the SSE instruction set does not apply to double precision floating point instructions, which re-quire SSE2. 32-bit instructions are available in 80386 and later. 64-bit instructions …
