ABSTRACT:
A distribution mechanism includes a scheduling device which partitions a common timing signal with a period T into n slots of t duration each, a configuration table having n addressable locations with each of the n locations storing communication control information and addressable by slot numbers generated by the scheduling device and a distribution buffer device (2) having at least a first and a second part, with each part having n addressable locations addressed by control information provided by the configuration table during each slot period to cause an interface involved in the to be established communications during a selected slot period, to write the information to be transmitted in one part of the distribution buffer and the information to be received by the interface to be read from the other part of the distribution buffer at addresses derived from the communication control information and the slot generated by the schedule means.
