Abstract
A method and apparatus for prefetching data in computer systems that tracks the number of prefetches currently active and compares that number to a preset maximum number of allowable prefetches to determine if additional prefetches should currently be performed. By limiting the number of prefetches being performed at any given time, the use of system resources for prefetching can be controlled, and thus system performance can be optimized.
