Abstract
An system for prefetching data for a processor includes a processor core, a memory, a cache memory, and a prefetch circuit. The memory may be configured to store information for use by the processor core. The cache memory may be configured to issue a fetch request for information from the memory for use by the processor core. The prefetch circuit may be configured to issue a prefetch request for information from the memory to store in the cache memory using a predicted address, and to monitor, over a particular time interval, an amount of fetch requests from the cache memory and prefetch requests from the prefetch circuit. The prefetch circuit may also be configured to disable prefetch requests from the memory for a subsequent time interval in response to a determination that the amount satisfies a threshold amount.
