Abstract:
Aspects include computing devices, systems, and methods for partitioning a system cache by sets and ways into component caches. A system cache memory controller may manage the component caches and manage access to the component caches. The system cache memory controller may receive system cache access requests specifying component cache identifiers, and match the component cache identifiers with records correlating traits of the component cache identifiers with in a component cache configuration table. The component cache traits may include a set shift trait, set offset trait, and target ways, which may define the locations of the component caches in the system cache. The system cache memory controller may also receive a physical address for the system cache in the system cache access request, determine an indexing mode for the component cache, and translate the physical address for the component cache.
