PAVG.{UB/SH} – Packed Average
Architecture revision:
Architecture revision1 and higher.
Description
Computes the average of pairs of packed unsigned bytes (pavg.ub) or packed signed halfwords
(pavg.sh). The averages are computed by adding two values together while also adding in a
rounding factor in the least significant bit. The result is then halved by shifting it one position to
the right.
