    Abstract: A cache controller adaptively partitions a shared cache. The adaptive partitioning cache controller includes tag comparison and staling logic and selection logic that are responsive to client access requests and various parameters. A component cache is assigned a target occupancy which is compared to a current occupancy. A conditional identification of stale cache lines is used to manage data stored in the shared cache. When a conflict or cache miss is identified, selection logic identifies candidates for replacement preferably among cache lines identified as stale. Each cache line is assigned to a bucket with a fixed number of buckets per component cache. Allocated cache lines are assigned to a bucket as a function of the target occupancy. After a select number of buckets are filled, subsequent allocations result in oldest cache lines being marked stale. Cache lines are deemed stale when their respective component cache active indicator is de-asserted.

    缓存控制器自适应地分区共享缓存。 自适应分区高速缓存控制器包括响应于客户端访问请求和各种参数的标签比较和陈述逻辑和选择逻辑。 组件高速缓存被分配一个与当前占用率进行比较的目标占用率。 使用陈旧缓存行的条件标识来管理存储在共享缓存中的数据。 当识别冲突或高速缓存未命中时，选择逻辑优选在被标识为陈旧的高速缓存行中标识替换的候选者。 每个缓存行都分配给每个组件缓存具有固定数量的存储桶的存储桶。 分配的缓存线被分配给一个桶作为目标占用的函数。 在选定数量的桶被填满之后，后续的分配导致最早的高速缓存行被标记为陈旧。 当其各自的组件高速缓存活动指示器被取消断言时，高速缓存行被视为陈旧。

    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: 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.
