Abstract
In a data processing system comprising a first cache operable to store data for use when performing a data processing operation, and a second cache operable to store data required for fetching data into the first cache from memory, when it is determined that there is no entry for data for a data processing operation in the first cache, an entry in the first cache is allocated for the required data, and information that indicates an entry in the second cache for data required for fetching the required data is stored in the tag portion of the allocated entry. Then, once a request has been sent to a memory system for the required data, the information in the tag portion for the allocated entry in the first cache that indicates an entry in the second cache is replaced with information indicative of an address for the data required for fetching the required data.
