  • CPU activity monitoring through cache watching
    Patent number: 5564015
    Abstract: 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.
