Abstract:
A processing system monitors memory bandwidth available to transfer data from memory to a cache. In addition, the processing system monitors a prefetching accuracy for prefetched data. If the amount of available memory bandwidth is low and the prefetching accuracy is also low, prefetching can be throttled by reducing the amount of data prefetched. The prefetching can be throttled by changing the frequency of prefetching, prefetching depth, prefetching confidence levels, and the like.
