Title: Apparatus and methods to reduce castouts in a multi-level cache hierarchy
Inventor: SPEIER THOMAS PHILIP
IPC: G06F12/00
Filed: 2008-01-30
Abstract: Techniques and methods are used to reduce allocations to a higher level cache of cache lines displaced from a lower level cache. When it is determined that displaced lines have already been allocated in a higher level, the allocations of the displaced cache lines are prevented in the next level cache, thus, reducing castouts. To such ends, a line is selected to be displaced in a lower level cache. Information associated with the selected line is identified which indicates that the selected line is present in a higher level cache. An allocation of the selected line in the higher level cache is prevented based on the identified information. Preventing an allocation of the selected line saves power that would be associated with the allocation.
