A.5.36 CVTDQ2PS: Packed Signed INT32 to Packed Single-Precision FP
Conversion
CVTDQ2PS xmm1,xmm2/mem128 ; 0F 5B /r [WILLAMETTE,SSE2]
CVTDQ2PS converts four packed signed doublewords from the source operand
to four packed single-precision FP values in the destination operand.
The destination operand is an XMM register. The source can be either an
XMM register or a 128-bit memory location.
