    Abstract: Aspects include computing devices, systems, and methods for implementing a cache maintenance or status operation for a component cache of a system cache. A computing device may generate a component cache configuration table, assign at least one component cache indicator of a component cache to a master of the component cache, and map at least one control register to the component cache indicator by a centralized control entity. The computing device may store the component cache indicator such that the component cache indicator is accessible by the master of the component cache for discovering a virtualized view of the system cache and issuing a cache maintenance or status command for the component cache bypassing the centralized control entity. The computing device may receive the cache maintenance or status command by a control register associated with a cache maintenance or status command and the component cache bypassing the centralized control entity.

    Abstract: A transparent format converter (TFC) may determine that a request by at least one processor for graphics data stored in graphics memory is indicative of a request for graphics data in a first data format. The TFC may retrieve the graphics data in a second data format from the graphics memory based at least in part on the request for the graphics data in the graphics memory. The TFC may convert the retrieved graphics data from the second data format to the first data format. The TFC may store the converted graphics data in the first data format into a memory that is accessible by the at least one processor.

    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.
