Abstract
Methods and apparatus provide monitoring of memory access traffic in a data processing system by tracking, such as by data fabric hardware control logic, a number of cache line accesses to a page of memory associated with one or more memory devices, and producing spike indication data that indicates a spike in cache line accesses to a given page of memory. Pages are moved from a slower memory to a faster memory based on the spike indication data. In some implementations, the tracking is done by updating a cache directory with data representing the tracked number of cache line accesses.
