ABSTRACT:
A processor bus linked with at least a processor, a memory bus linked with a main memory, and a system bus linked with at least an input/output device are connected to a three-way connection control system. The control system includes a bus-memory connection controller connected to address buses and control buses respectively of the processor, memory, and system buses to transfer address and control signals therebetween. The control system further includes a data path switch connected to data buses respectively of the processor, memory, and system buses to transfer data via the data buses therebetween depending on the data path control signal.
