Synopsis
_mm512_mask_cvtepi32_storeu_epi8(void* base_addr, __mmask16 k, __m512i a);
Description
Convert packed 32-bit integers in "a" to packed 8-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 15
i := 32*j
l := 8*j
IF k[j]
MEM[base_addr+l+7:base_addr+l] := Truncate8(a[i+31:i])
FI
