Abstract

A buffer is configured to store a plurality of last addresses accessed by a processor core from a memory. A minimum distance extraction circuit determines distances of a current memory address accessed by the processor core from each of the plurality of last addresses in the buffer and determines a minimum distance from the distances. A limit determination circuit compares the minimum distance to each of a plurality of ranges of distances and selects a range of the plurality of ranges within which the minimum distance falls. Each of a plurality of counters of a counter circuit is associated with a corresponding one of the plurality of ranges. A counter of the plurality of counters is to be incremented corresponding to the selected range.
