VCVTPS2PHX xmm {z}, xmm
Synopsis
_mm_maskz_cvtxps_ph(__mmask8 k, __m128 a);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed half-precision (16-bit) floating-point elements, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). The upper 64 bits of "dst" are zeroed out.
Operation
FOR j := 0 to 3
IF k[j]
dst.fp16[j] := Convert_FP32_To_FP16(a.fp32[j])
ELSE
dst.fp16[j] := 0
FI
ENDFOR
dst[MAX:64] := 0
