UNPCKHPD
Usage: UNPCKHPD dest,src Modifies flags: None
Interleaved unpacking of the high double-precision floating-point values from the 'src' operand and the 'dest'.
Unpack and Interleave High Packed Double-Precision FP Values
UNPCKHPD xmm1,xmm2/m128 ; 66 0F 15 /r [WILLAMETTE,SSE2]
UNPCKHPD 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[63-0] := dst[127-64];
dst[127-64] := src[127-64].
The 'src operand can be an XMM register or a 128-bit memory location; the 'dest' operand is an XMM register.
EXAMPLE:
