A.5.325 UNPCKLPS: Unpack and Interleave Low Packed Single-Precision FP Data
UNPCKLPS xmm1,xmm2/m128 ; 0F 14 /r [KATMAI,SSE]
UNPCKLPS performs an interleaved unpack of the low-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[31-0];
dst[63-32] := src[31-0];
dst[95-64] := dst[63-32];
dst[127-96] := src[63-32].
