Abstract
A microprocessor includes a first hardware data prefetcher that prefetches data into the microprocessor according to a first algorithm. The microprocessor also includes a second hardware data prefetcher that prefetches data into the microprocessor according to a second algorithm, wherein the first and second algorithms are different. The second prefetcher detects that it is prefetching data into the microprocessor according to the second algorithm in excess of a first predetermined rate and, in response, sends a throttle indication to the first prefetcher. The first prefetcher prefetches data into the microprocessor according to the first algorithm at below a second predetermined rate in response to receiving the throttle indication from the second prefetcher.
