ABSTRACT:
An integrated circuit having a plurality of modules and an internal communication bus interconnecting the modules is arranged to produce an output indicating which module is granted access to the bus at the time. A control means grants to a module access to the bus in response to a request from the module on the basis of the priority of its request amongst any other requests for access. The control means produces the output indication in digital form which is multiplexed with other data from the bus at an output port of the integrated circuit.
