产生用于共享高速缓冲存储器系统的近似使用测量
摘要：
本发明揭示产生用于共享高速缓冲存储器系统的近似使用测量。在一个方面中，提供高速缓冲存储器系统。所述高速缓冲存储器系统包括共享高速缓冲存储器系统。所述共享高速缓冲存储器系统的子集包括经配置以存储针对QoS类别的QoSID跟踪指示符的服务质量标识符QoSID跟踪标签。所述共享高速缓冲存储器系统进一步包括高速缓存控制器，其经配置以接收包括QoSID的存储器存取请求，且经配置以存取对应于所述存储器存取请求的高速缓存线。所述高速缓存控制器还经配置以确定所述存储器存取请求的所述QoSID是否对应于指派到所述QoSID的高速缓存线。如果确定为“是”，那么所述高速缓存控制器另外经配置以更新所述QoSID跟踪标签。
摘要（英）：

Generating approximate usage measurements for shared cache memory systems is disclosed. In one aspect, a cache memory system is provided. The cache memory system comprises a shared cache memory system. A subset of the shared cache memory system comprises a Quality of Service identifier (QoSID) tracking tag configured to store a QoSID tracking indicator for a QoS class. The shared cache memory system further comprises a cache controller configured to receive a memory access request comprising a QoSID, and is configured to access a cache line corresponding to the memory access request. The cache controller is also configured to determine whether the QoSID of the memory access request corresponds to a cache line assigned to the QoSID. If so, the cache controller is additionally configured to update the QoSID tracking tag.
