Instruction
VPMOVSWB m64 {k}, xmm
Synopsis
 _mm_mask_cvtsepi16_storeu_epi8(void* base_addr, __mmask8 k, __m128i a);
Description
Convert packed signed 16-bit integers in "a" to packed 8-bit integers with signed saturation, 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 7
	i := 16*j
	l := 8*j
	IF k[j]
		MEM[base_addr+l+7:base_addr+l] := Saturate8(a[i+15:i])
	FI
