Abstract

A computer implemented method for prefetching data for a processor into a first memory, wherein in a recording mode, a prefetching unit for a processor performs the steps of a method. The method includes: receiving one or more first addresses from the processor; filtering the one or more first addresses; providing a recording-list including the filtered one or more first addresses; receiving at least one second address from the processor; receiving a playback-list including all or a subset of the first addresses of the recording-list; comparing the at least one second address with each of the first addresses in the playback-list for identifying a matching address; if a matching address is identified, fetching data from a second memory; and transferring the fetched data to a first memory.
