ABSTRACT:
The present invention is directed to a method for arbitrating for control of a bus in a multiprocessor system. The multiprocessor system comprises a plurality of processors and a main memory coupled to one another by the bus, each processor including a cache memory accessible by the corresponding processor and in connection with transactions on the bus. The method includes the steps of generating requests for control of the bus and granting control of the bus in respect of one of the requests. The bus is monitored for preselected transaction activity on the bus; and an idle cycle is inserted on the bus upon monitoring the preselected transaction activity.
