Abstract
A programmable communications processor is coupled to execute instructions of programs designed to process the transfer of information between a plurality of communication channels and a main memory included in the system. A software implemented and controlled pause counter enables the execution of a given maximum number of instructions for servicing, for example, a communication channel following which it suspends or pauses such servicing, in order to service another higher priority request which may be pending. Processing of lower priority service requests thus cannot delay the recognition and handling of higher priority requests for more than a minimum period of time and the effective throughput rate is increased.
