A.5.42 CVTPS2DQ: Packed Single-Precision FP to Packed Signed INT32
Conversion
CVTPS2DQ xmm1,xmm2/mem128 ; 66 0F 5B /r [WILLAMETTE,SSE2]
CVTPS2DQ converts four packed single-precision FP values from the source
operand to four packed signed doublewords 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.
