Interbus data flow control system for realigning data by byte swapping and byte sampling

摘要

A system and method for controlling a data flow between data buses having different characteristics includes a first bus, a first interface coupled to the first bus, a second bus, a second interface coupled to the second bus, a byte selection unit coupled to the first and second interfaces and transferring data from the first interface to the second interface, or from the second interface to the first interface according to a control signal, and a byte selection control unit storing a plurality of byte selection data and generating at least one of the plurality of byte selection data to the byte selection unit as the control signal. Each byte selection data representing a predetermined byte location.
