SSE4a

from Wikipedia, the free encyclopedia

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, MOVNTSDand 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.
