摘要： Aspects include computing devices, systems, and methods for dynamically 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 and reserve locations in the system cache corresponding to the component caches correlated with component cache identifiers of the requests. Reserving locations in the system cache may activate the locations in the system cache for use by a requesting client, and may also prevent other client from using the reserved locations in the system cache. Releasing the locations in the system cache may deactivate the locations in the system cache and allow other clients to use them. A client reserving locations in the system cache may change the amount of locations it has reserved within its component cache.

摘要翻译： 方面包括计算设备，系统和方法，用于通过集合和方式动态地将系统高速缓存分区到组件高速缓存中。 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系统高速缓存访​​问请求，并且在系统高速缓存中保留对应于与请求的组件高速缓存标识符相关联的组件高速缓存的位 在系统缓存中预留位置可以激活系统高速缓存中的位置以供请求客户端使用，并且还可以防止其他客户端使用系统高速缓存中的保留位置。 释放系统缓存中的位置可以停用系统缓存中的位置，并允许其他客户端使用它们。 保留系统缓存中的位置的客户端可以改变其在其组件高速缓存中保留的位置的数量。
