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 18):
A method of operating a system cache to provide data caching in response to data access requests from plural system components, the method comprising the steps of:\n storing blocks of data items in plural entries of data caching storage, 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; storing sets of sector use patterns in a set of pattern entries and in response to a data access request received from a system component specifying one or more data items selecting a selected pattern entry in dependence on a system component identifier in the data access request, and generating a sector use prediction in dependence on the sector use pattern in the selected pattern entry; and retrieving one or more further data items in dependence on the sector use prediction.
