ABSTRACT:
A multi-cache data storage system has a number of cache units and a main memory. The caches are addressed by a virtual address. When data is updated in one of the caches, the virtual address is translated into a physical address and sent to the main memory over a bus, along with the updated data value. Each cache continuously monitors the bus for updates from other caches and checks whether it holds a data item corresponding to the physical address. If so, the data item is updated or invalidated, so as to ensure cache coherency.
