Abstract
A digital data processing system including an interconnection for the various elements that constitute the system. Each element that connects to the interconnection is called a nexus, and each nexus in the system can communicate with other nexuses. A central clocking circuit generates timing signals that control such communications on a synchronous basis. The clocking circuit includes oscillator, control and sequencing circuits that produce phase and clocking signals that are coupled to each nexus. Each nexus contains receivers and decoders for converting the phase and clocking signals into a sequence of internal timing signals that synchronizes the operation of the nexus to transfers among the nexuses.
