Abstract: A method for improving the performance of an existing busoriented computer system with minimum or no design change to the existing hardware, bus protocol, or bus operation is disclosed. Specifically, the present invention improves the effective bandwidth of an existing bus architecture by creating multiple physical instantiations of the existing bus and directing traffic onto these different buses based on the type of bus operation being performed. This results in multiple components having the capability to simultaneously perform bus operations, therefore improving the effective bandwidth of the system. This invention also allows the components which are current being utilized in the existing bus architecture to be re-utilized with minimum additional external logic.
