PURPOSE:To determine the priority for practicality, by checking career of each signal, when a plurality of request signals are generated in competition. CONSTITUTION:The system consists of a count circuit counting the number of usage request for a plurality of processors and a control means giving usage permission to the processor having the maximum number. When a resource request is given from processors 100-N100, it is counted at counter circuits 110-N10. If the requests from a plurality of processors are competed, the counter circuit indicating a maximum value is detected at a maximum value detecting circuit 10. The comparison is made at comparison circuits 120-N20. Usage permission signal is transmitted from a common control section for the processor only indicating the maximum number. |
