PADDSUBS.{UH/SH} – Packed Halfword Addition and Subtraction with Sat-
uration
Architecture revision:
Architecture revision1 and higher.
Description
Perform an addition and subtraction on the same halfword operands which are selected from the
source registers. The resulting halfwords are saturated to unsigned halfwords (paddsubs.uh) or
signed halfwords (paddsubs.sh) and then packed together in the destination register.
Operation:

Operands:
I,II.

Rd[31:16] ← SATU(ZE(operand1, 17) + ZE(operand2, 17), 16);
