A.5.41 CVTPI2PS: Packed Signed INT32 to Packed Single-FP Conversion
CVTPI2PS xmm,mm/mem64 ; 0F 2A /r [KATMAI,SSE]
CVTPI2PS converts two packed signed doublewords from the source operand
to two packed single-precision FP values in the low quadword of the
destination operand. The high quadword of the destination remains
unchanged.
The destination operand is an XMM register. The source can be either an
MMX register or a 64-bit memory location.
