Synopsis
_mm256_mask_cvtepi32_ph(__m128h src, __mmask8 k, __m256i a);
Description
Convert packed signed 32-bit integers in "a" to packed half-precision (16-bit) floating-point elements, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 TO 7
IF k[j]
dst.fp16[j] := Convert_Int32_To_FP16(a.dword[j])
ELSE
dst.fp16[j] := src.fp16[j]
FI
ENDFOR
dst[MAX:128] := 0
