Abstract:
A computer system comprising:a first master device coupled to a first bus and configured to convey data of a first predetermined width on said first bus;a first slave device coupled to a second bus and configured to receive data of a second width on said second bus;a second slave device coupled to a third bus and configured to receive data of a third width on said third bus, wherein said first predetermined width is different from at least said second width or said third width;a data path switching unit coupled to said first bus, said second bus and said third bus and configured to provide a data transfer path from said first bus to said second bus and said third bus depending upon a data path control signal, wherein said data path switching unit communicates data from said first bus to said second bus without transferring data through said third bus, and wherein said data path switching unit communicates data from said first bus to said third bus without transferring data through said second bus; anda system controller configured to determine said second width of said second bus and said third width of said third bus in response to a predetermined trigger initiated during an operation of said computer system, and configured to output said data path control signal to control said data path switching unit in dependence upon said second and third widths.
