Abstract
An interconnect controller is coupled to a cache and coupled to a plurality of masters and configured to receive a cache access packet from a master. The cache access packet includes a first master identifier to identify the master, a first sub-cache index identifier to identify a slice of the cache, and an operation to be performed on the cache. A mapping table has master identifiers associated with sub-cache index identifiers and compare logic compares the first master identifier and the first sub-cache index identifier to the mapping table. The interconnect controller rejects the cache access packet in response to the first master identifier not being associated with the first sub-cache index identifier in the mapping table.
