A.5.323 UNPCKHPS: Unpack and Interleave High Packed Single-Precision FP
Values
UNPCKHPS xmm1,xmm2/m128 ; 0F 15 /r [KATMAI,SSE]
UNPCKHPS performs an interleaved unpack of the high-order data elements
of the source and destination operands, saving the result in "xmm1". It
ignores the lower half of the sources.
The operation of this instruction is:
dst[31-0] := dst[95-64];
dst[63-32] := src[95-64];
dst[95-64] := dst[127-96];
dst[127-96] := src[127-96].
