SSE Shuffle instructions
SHUFPS is able to shuffle any of the
numbers from one source operand to the lower two destination fields; the
upper two destination fields are generated from a shuffle of any of the
four SP FP numbers from the second source operand. By using the same register
for both sources, SHUFPS can return any combination of the four SP FP numbers
from this register.
UNPCKHPS performs an interleaved unpack
of the high-order data elements of first and second packed operands,and
it ignores the lower half part of the sources.
