A central processing unit ("CPU") activity monitor and method provides CPU activity information. The CPU activity monitor includes a timer and an activity event counter for receiving a plurality of mode signals from the CPU, a cache miss signal from a cache memory system, and a clock signal from a clock. An activity-to-inactivity value defines when the CPU transitions from an active state to an inactive state. An activity threshold defines when the CPU transitions from an inactive state to an active state. |
