Instruction
VMULPS xmm {k}, xmm, xmm
Synopsis
_mm_mask_mul_ps(__m128 src, __mmask8 k, __m128 a, __m128 b);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
i := j*32
IF k[j]
dst[i+31:i] := a[i+31:i] * b[i+31:i]
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:128] := 0
