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. For one element to communicate with another element, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection. If the command is to initiate the retrieval of information from the other element, the other element stores the command and address information in a storage file. The storage file can accumulate a number of commands and related addresses thereby to allow the different commanding nexuses to initiate similar transfers from a single one of the other elements without producing a busy indication.
