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