Dynamic cache sharing based on power state

摘要

In one embodiment, the present invention includes a cache, compute engines connected to the cache, and a way mask disposed between the cache and the compute engines. This way mask may be partitioned into ways. Some of the ways may be dedicated to only one of the compute engines and other ways can be shared among more than one of the compute engines. Other embodiments are described and claimed.

1. A system comprising:
a cache; compute engines connected to said cache; cache allocation logic associated with a way mask disposed between said cache and said compute engines, said way mask partitioned into ways, wherein some ways are dedicated to only one of said compute engines and other ways are shared among more than one of said compute engines; a power control unit to monitor a power state of said compute engines and to update said way mask based on said power state of said compute engines.
