Programmable cache for the partitioning of local and remote cache blocks

摘要

A cache comprises a memory including a plurality of entries and a circuit. Each entry of the plurality of entries is configured to store a cache block. The circuit is configured to select a first entry of the plurality of entries to store a first cache block. In one implementation, the first cache block corresponds to a first transaction initiated by a first agent, wherein the first entry is selected from a first subset of the plurality of entries indicated as selectable for the first agent. In another implementation, the circuit is configured to select the first entry of the plurality of entries in response to whether the first cache block is a remote cache block or a local cache block. In other implementations, the circuit may be configured to handle a combination of the above.
