VMULPH xmm {k}, xmm, xmm
Synopsis
_mm_mask_mul_ph(__m128h src, __mmask8 k, __m128h a, __m128h b);
Description
Multiply packed half-precision (16-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 i := 0 TO 7
IF k[i]
dst.fp16[i] := a.fp16[i] * b.fp16[i]
ELSE
dst.fp16[i] := src.fp16[i]
FI
ENDFOR
dst[MAX:128] := 0
