Abstract:
A system cache and method of operating a system cache are provided. The system cache provides data caching in response to data access requests from plural system components. The system cache has data caching storage with plural entries, each entry storing a block of data items and each block of data items comprising plural sectors of data items, and each block of data items being stored in an entry of the data caching storage with an associated address portion. Sector use prediction circuitry is provided which has a set of pattern entries to store a set of sector use patterns. In response to a data access request received from a system component specifying one or more data items a selected pattern entry is selected in dependence on a system component identifier in the data access request and a sector use prediction is generated in dependence on a sector use pattern in the selected pattern entry. Further data items may then be retrieved which are not specified in the data access request but are indicated by the sector use prediction, and memory bandwidth usage is thereby improved.

Claim (Index 3):
The system cache as claimed in  claim 1 , wherein the data retrieval circuitry is responsive to a miss signal from the data caching storage to cause the data caching storage to allocate an entry with an address portion taken from the data access request and to initiate a data filling process for the entry comprising retrieving the one or more data items specified in the data access request and subsequently, when a memory access bandwidth criterion is satisfied, initiating a further data filling process for the entry to retrieve the one or more further data items indicated by the sector use prediction.
