  • Generating simulated stall signals based on access speed model or history of requests independent of actual processing or handling of conflicting requests
    Patent number: 8918786
    Abstract: A multiprocessing system executes a plurality of processes concurrently. A process execution circuit (10) issues requests to access a shared resource (16) from the processes. A shared access circuit (14) sequences conflicting ones of the requests. A simulating access circuit (12) generates signals to stall at least one of the processes at simulated stall time points selected as a predetermined function of requests from only the at least one of the processes and/or the timing of the requests from only the at least one of the processes, irrespective of whether said stalling is made necessary by sequencing of conflicting ones of the requests. Thus, part from predetermined maximum response times, predetermined average timing can be guaranteed, independent of the combination of processes that is executed.
