Abstract
Partition information includes entries that each include an entity identifier and associated cache configuration information. A controller manages memory requests originating from processor cores, including: comparing at least a portion of an address included in a memory request with tags stored in a cache to determine whether the memory request results in a hit or a miss, and comparing an entity identifier included in the memory request with stored entity identifiers to determine a matched entry. The cache configuration information associated with the entity identifier in a matched entry is updated based at least in part on a hit or miss result. The associated cache configuration information includes cache usage information that tracks usage of the cache by an entity associated with the particular entity identifier, and partition descriptors that each define a different group of one or more of the regions.
