PADDS.{UB/SB/UH/SH} – Packed Addition with Saturation
Architecture revision:
Architecture revision1 and higher.
Description
Perform addition of four pairs of packed bytes or two pairs of halfwords. The result is saturated to
either unsigned bytes (padds.ub), signed bytes (padds.sb), unsigned halfwords (padds.uh) or
signed halfwords (padds.sh).
Operation:
