Abstract

In one embodiment, a multi-core processor includes multiple cores and an uncore, where the uncore includes various logic units including a cache memory, a router, and a power control unit (PCU). The PCU can clock gate at least one of the logic units and the cache memory when the multi-core processor is in a low power state to thus reduce dynamic power consumption.
