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. Sector use prediction circuitry is provided which stores a set of sector use pattern entries. In response to a data access request received from a system component specifying one or more data items, a pattern entry is selected 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.
