    Abstract: PURPOSE: A cache phase detector and a processor core are provided to effectively utilize critical section cache, thereby reducing power consumption. CONSTITUTION: A counting unit(110) enables a tag corresponding to a request generated in a processor core to generate a critical section miss count by counting a tag miss request which includes an effective cache line based on a tag miss signal which includes critical section cache and a cache line valid signal which includes availability of the cache line corresponding to the request. A signal generation unit(130) compares the critical section miss count with a standard value.

    Abstract: PURPOSE: A multiprocessor, cache coherence management apparatus for the same, and method thereof are provided to prevent the generation of unnecessary transaction between multiprocessors. CONSTITUTION: A ping pong monitoring unit(110) monitors a ping pong migration sequence between processors. A counting unit(130) counts the number of the ping pong migration sequences in response to a monitoring result. A request modifying unit(150) changes a migration request into a non-migration sharing method request based on a count result.
