Abstract
A method and apparatus for controlling a frequency of CMI are disclosed. The method may include classifying request types into one or more request groups, wherein each of the request types is a type of CMI request. A number of clock cycles that is sufficient to process a request in each request group may be assigned, and requests that are made to CMI may be monitored with one or more performance counters. A number of requests that occur during a length of time in each request group may be determined, and a frequency of the CMI may be periodically adjusted based upon the number of requests occurring per second in each request group and the assigned number of clock cycles per request for each request group.
