Instruction
VPEXPANDW xmm {z}, m128
Synopsis
_mm_maskz_expandloadu_epi16(__mmask8 k, const void* mem_addr);
Description
Load contiguous active 16-bit integers from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 7
i := j*16
IF k[j]
dst[i+15:i] := MEM[mem_addr+m+15:mem_addr+m]
m := m + 16
ELSE
dst[i+15:i] := 0
FI
ENDFOR
dst[MAX:128] := 0
