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.

Abstract translation: 方面包括计算设备，系统和用于通过集合和方式将系统高速缓存分组到组件高速缓存中的方法。 系统高速缓冲存储器控制器可以管理组件高速缓存并管理对组件高速缓存的访问。 系统高速缓冲存储器控制器可以接收指定组件高速缓存标识符的系统高速缓存访​​问请求，并且将组件高速缓存标识符与组件高速缓存标识符的特征与组件高速缓存配置表相关联的记录进行匹配。 组件缓存特征可以包括设置的移动特征，设置偏移特征和目标方式，其可以定义系统高速缓存中的组件高速缓存的位置。 系统高速缓冲存储器控制器还可以在系统高速缓存访​​问请求中接收系统高速缓存的物理地址，确定组件高速缓存的索引模式，并转换组件高速缓存的物理地址。
