SSE4a
SSE4a ( Streaming SIMD Extensions 4a ) is an instruction set extension from AMD for x86 processors. It complements in K10 processors existing SSE3 instruction set to the four commands EXTRQ
, INSERTQ
, MOVNTSD
and MOVNTSS
. Despite the similar name, SSE4a has nothing to do with Intel's SSE4 instruction set extension . The only thing they have in common is that both are based on SSE3.
