PSUBXH.SH – Packed Signed Halfword Subtraction with Crossed Operand
and Halving
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 halved in order to avoid any overflow and
then packed together in the destination register.
Operation:
I.
Syntax:
