PSUBXS.{UH/SH} – Packed Halfword Subtraction with Crossed Operand
and Saturation
Architecture revision:
Architecture revision1 and higher.
Description
Subtract the bottom halfword of Ry from the top halfword of Rx and the top halfword of Ry from
the bottom halfword of Rx. The resulting halfwords are saturated to unsigned halfwords
(psubxh.uh) or signed halfwords (psubxh.sh) and then packed together in the destination regis-
ter.
