Instruction
VPMOVDW m64 {k}, xmm
Synopsis
_mm_mask_cvtepi32_storeu_epi16(void* base_addr, __mmask8 k, __m128i a);
Description
Convert packed 32-bit integers in "a" to packed 16-bit integers with truncation, and store the active results (those with their respective bit set in writemask "k") to unaligned memory at "base_addr".
Operation
FOR j := 0 to 3
i := 32*j
l := 16*j
IF k[j]
MEM[base_addr+l+15:base_addr+l] := Truncate16(a[i+31:i])
FI
ENDFOR
