Synopsis
_mm_mask_cvtepu32_ph(__m128h src, __mmask8 k, __m128i a);
Description
Convert packed unsigned 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). The upper 64 bits of "dst" are zeroed out.
Operation
FOR j := 0 TO 3
IF k[j]
dst.fp16[j] := Convert_Int32_To_FP16(a.dword[j])
ELSE
dst.fp16[j] := src.fp16[j]
FI
ENDFOR
dst[MAX:64] := 0
