Abstract
A bi-directional data path apparatus coupled between a first bus and a second bus for allowing a plurality of data transfering devices contained on either one of the buses to transfer data to the devices contained on the other bus. The data path apparatus includes latching stations designed to receive data from the first and second buses. The data path apparatus includes a plurality of byte lanes interconnecting the byte latching stations. A control mechanism directs the transfer of data along specific byte lanes and in a specific temporal order depending on the databus size of the devices sending and receiving data.
