  • Multiprocessor system having time slice bus arbitration for controlling bus access based on determined delay time among processors requesting access to common bus
    Patent number: 5283902
    Abstract: A method and device operate a system that contains several processors with different priority rankings. The overall system starts its operation as an arbitrating system. The conflict time resulting from a simultaneous request is determined, in each case, and a delay of the processing cycle of the subordinate conflicting processor by precisely this waiting time, takes place. With this, the system operates in time slice control, where the arbitration remains active in the background and intervenes, if necessary. The waiting times of the processors are thereby minimized.
