PADDXH.SH – Packed Signed Halfword Addition with Crossed Operand
and Halving
Architecture revision:
Architecture revision1 and higher.
Description
Add together the top halfword of Rx with the bottom halfword of Ry and the bottom halfword of
Rx with the top halfword of Ry. The resulting halfwords are halved in order to avoid any overflow
and then packed together in the destination register.
Operation:
I.
Syntax:
