ABSTRACT:
A compressed I/O bus system for a general-purpose computer multiplexes 32 bit data and addresses on 32 of 42 dedicated parallel signal paths, and optimizes the bus structure by mapping bus requests made by peripheral devices to "high" memory portions of system RAM not dedicated to other purposes. In one aspect a bus controller is programmable to select translation routines stored in system RAM allowing various models and types of CPUs to be supported. Supported CPUs are interchangeable in the system. In another aspect a default interface attached to the compressed I/O bus of the invention, and translates bus states between the optimized compressed bus and one of an ISA bus or an EISA bus.
