Interbus buffer for use between a pseudo little endian bus and a true little endian bus

摘要

An interbus buffer (18) coordinates data transfers between two different sized buses. The first bus (processor bus) allows data to be ordered according to either a big endian protocol or a "munged" little endian mode. The second bus (local bus) allows data to be ordered according to either a big endian protocol or a true little endian mode but does not define a transaction size. The disclosed interbus buffer coordinates interbus data transfers in spite of the variety of different transaction sizes and operating modes.
