Abstract
A computer implemented method for prefetching data. The method includes: receiving one or more addresses by a prefetching unit upon execution of an enqueuing command in a first piece of program logic; enqueuing each of the received addresses to a recording-list; identifying one of the positions in the recording-list as jump position; providing the identified jump position to a frame-shifter; using a sub-list of the recording-list defined by a shiftable frame as a playback-list; executing a frame-shift command which triggers the frame-shifter to shift the frame in dependence on the jump position to provide an updated playback-list; fetching data identified by the updated playback-list from a second memory; and transferring the fetched data to a first memory.
