A data processing system including a central processing unit and control circuitry on a single chip connected by a common bus to two or more bus devices having different sets of bus parameters. A first set of bus parameters functions as a memory bus for transfers to and from main memory, a second set of bus parameters functions as an I/O bus for I/O device transfers and a third set of bus parameters functions as a video bus for transfers to a video display. Each set of bus parameters has different timing selected to maximize transfers for the particular bus function (main memory, I/O, video or other) implemented by the bus parameters.
