Abstract:
In an embodiment, a processor includes multiple tiles, each including a core and a tile cache hierarchy. This tile cache hierarchy includes a first level cache, a mid-level cache (MLC) and a last level cache (LLC), and each of these caches is private to the tile. A controller coupled to the tiles includes a cache power control logic to receive utilization information regarding the core and the tile cache hierarchy of a tile and to cause the LLC of the tile to be independently power gated, based at least in part on this information. Other embodiments are described and claimed.
