Abstract
Prefetch circuitry is provided which is responsive to a determination that the memory address of a data value specified by a current access request is the same as a predicted memory address, to perform either a first prefetch linefill operation or a second prefetch linefill operation to retrieve from memory at least one further data value in anticipation of that data value being the subject of a subsequent access request. The selection of either the first prefetch linefill operation or the second prefetch linefill operation is performed in dependence on an attribute of the current access request.
