摘要:
A method for implementing a software-managed cache comprises determining an object identifier (ID) for each of a first set of objects of a plurality of objects resident in a local memory, to generate a first cache table, the first cache table comprising a plurality of entries. Each object comprises an object ID and an effective address. The method receives a request for an object, the request comprising an object ID. The method compares the received object ID with the entries in the first cache table. In the event the received object ID matches an entry in the first cache table, the method returns the matching entry in response to the request. In the event the received object ID does not match an entry in the first cache table, the method calculates an effective address in the local memory of the object associated with the object ID.
