    摘要: In a data.processing system in which a plurality of data processing units, as well as the main memory unit, are coupled to a system bus, the utilization of the system bus is Increased to such an extent that each of a plurality of cache memory units coupled to the system bus can have a plurality of data processing units associated therewith. The system bus utilization is increased by dividing the system bus access operation into a plurality of sub-operations and by providing a defined cyclic sequence for the cache memory units to have access to the system bus.
