This simplified illustration of the MAM shows that it is made up of three 128-bit buffers. The Prefetch buffer eliminates any code fetch penalty for sequential instructions by loading four 32-bit (or eight 16-bit) words via the 128-bit wide interface to Flash. This is initiated as soon as Flash completes the previous access. The Branch Trail buffer captures the line when a code branch occurs. When the branch occurs again, those instructions are already available in the branch trail buffer. The Data Bypass buffer serves subsequent data requests which are satisfied from the Data Bypass latch if the data is sequential between the previously and next fetched data.
