9.3.6. Data Width Sizing
During the upsizing or downsizing process, transactions can also be resized using a data merging technique. For example, in the case of a 32-bit to 64-bit upsizing, if the size of each beat entering the bridge’s 32-bit interface is only two bytes, the bridge can merge up to four beats to form a single 64-bit beat. Similarly, in the case of a 128-bit to 64-bit downsizing, if the size of each beat entering the bridge’s 128-bit interface is only four bytes, the bridge can merge two beats to form a single 64-bit beat.
The bridges do not perform transaction merging for accesses marked as noncacheable.
