A.5.61 DIVPS: Packed Single-Precision FP Divide DIVPS xmm1,xmm2/mem128 ; 0F 5E /r [KATMAI,SSE] DIVPS divides the four packed single-precision FP values in the destination operand by the four packed single-precision FP values in the source operand, and stores the packed single-precision results in the destination register. The destination is an XMM register. The source operand can be either an XMM register or a 128-bit memory location. dst[0-31] := dst[0-31] / src[0-31], dst[32-63] := dst[32-63] / src[32-63], dst[64-95] := dst[64-95] / src[64-95], dst[96-127] := dst[96-127] / src[96-127].
