Abstract
A method and a switching system for connecting multiple requestors to multiple memory units simultaneously. This is accomplished by a switching system that employs multiplexing logic, control logic, multiple data input and output ports and a unique system interconnection topology. Independent data input ports comprised of multiplexing logic controlled by a control logic, simultaneously channel multiple fetch and store commands from the requestors to the memory units. Similarly, independent data output ports comprised of a second multiplexing logic controlled by a second control logic, simultaneously channels multiple return signals from the memory units to the requestors. The switching system of the present invention incorporates the unique system interconnection topology concept of feed-through boards and modular backplane boards. The feed-through boards coupled to the foreplane side of the backplane of a computer system and the modular backplane boards coupled to the backplane side of the backplane of a computer system, both serve to extend and manage the communication paths between the requestors and the memory units.
