Abstract
In a data processing system capable of concurrently executing multiple hardware threads of execution, an intermediate address translation unit in a processing unit translates an effective address for a memory access into an intermediate address. A cache memory is accessed utilizing the intermediate address. In response to a miss in cache memory, the intermediate address is translated into a real address by a real address translation unit that performs address translation for multiple hardware threads of execution. The system memory is accessed with the real address.
