Computer data routing system.

摘要

A digital computer system includes an interface for routing data which permits the transfer of data between mismatched devices. The computer system comprises a processor, memory and an interconnecting data bus, all configured to handle data units of a first data width. Also connected to the data bus is at least one I/O device configured to handle data units of a second data width. By adjusting the width of the data being transferred to match the width of the receiving device or bus, data may be transferred between devices of differing width. To adjust the width, control means are provided which modify the route along which data bytes are transferred based upon the width of the transferring and receiving devices and the direction of transfer are provided. <IMAGE>
