ABSTRACT:
A multiprocessor system includes a plurality of processors that share a multiple-way set-associative cache memory that includes a directory and a data array, the multiprocessor system being partitioned such that the plurality of processor operate as independent systems. The multiprocessor system also includes a hit judgement circuit that determines hits of, of the ways in the sets that are designated at the time a processor of a particular partition accesses the shared cache memory, only those ways that have been allocated in advance in accordance with active signals that are supplied as output at the time of the access.
