Instruction
VCVTPD2PS xmm {z}, xmm
Synopsis
_mm_maskz_cvtpd_ps(__mmask8 k, __m128d a);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed single-precision (32-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).
Operation
FOR j := 0 to 1
i := j*32
l := j*64
IF k[j]
dst[i+31:i] := Convert_FP64_To_FP32(a[l+63:l])
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:64] := 0
