Abstract

Processors in a telephone exchange are controlled by the arbitration system, which resolves conflicting requests for processor access to a shared resource. The arbitration units are connected via tri-state data busses to shared resources, and operate in parallel groups operating synchronously within each group. The units are connected in series in loops and an initialisation signal is made to propagate around the loop. When a demand signal is issued by a processor for access, a signal is transmitted on the bus to enter the arbitration loop circuit to reach that unit responsible for the processor. The signal is analysed in sync. and the resource unit is switched when access is authorised.
