Synopsis
_mm_maskz_cvtepu64_ph(__mmask8 k, __m128i a);
Description
Convert packed unsigned 64-bit integers 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 96 bits of "dst" are zeroed out.
Operation
FOR j := 0 TO 1
IF k[j]
dst.fp16[j] := Convert_Int64_To_FP16(a.qword[j])
ELSE
dst.fp16[j] := 0
FI
ENDFOR
dst[MAX:32] := 0
