3.17 SSE Instructions

SSE instructions are an extension of the SIMD execution model introduced with the MMX technology. SSE instructions are divided into four subgroups:

  • SIMD single-precision floating-point instructions that operate on the XMM registers

  • MXSCR state management instructions

  • 64–bit SIMD integer instructions that operate on the MMX registers

  • Instructions that provide cache control, prefetch, and instruction ordering functionality
