摘要： A method of providing requests to a cache pipeline includes receiving a plurality of requests from one or more state machines at an arbiter; selecting one of the plurality of requests as a selected request the selected request having been provided by a first state machine; determining that the selected request includes a mode that requires a first step and a second step, the first step including an access to a location in a cache; determining that the location in the cache is unavailable; and replacing the mode with a modified mode that only includes the second step.

摘要： A mechanism for dynamically altering a request received at a hardware component is provided. The request is received at the hardware component, and the request includes a mode option. It is determined whether an action of the request requires an unavailable resource and it is determined whether the mode option is for the action requiring the unavailable resource. In response to the mode option being for the action requiring the unavailable resource, the action is automatically removed from the request. The request is passed for pipeline arbitration without the action requiring the unavailable resource.

摘要： A mechanism for controlling data stream interruptions on a shared bus is provided. A first request is received to transfer data. High priority data components and low priority data components are determined for the first request. The high priority data components are transferred without interruptions. In response to receiving requests when transferring the high priority data components, the received requests are rejected.

摘要： Embodiments relate to storing data to a system memory. An aspect includes accessing successive entries of a cache directory having a plurality of directory entries by a stepper engine, where access to the cache directory is given a lower priority than other cache operations. It is determined that a specific directory entry in the cache directory has a change line state that indicates it is modified. A store operation is performed to send a copy of the specific corresponding cache entry to the system memory as part of a cache management function. The specific directory entry is updated to indicate that the change line state is unmodified.

摘要： System refresh in a cache memory includes generating a refresh time period (RTIM) pulse at a centralized refresh controller of the cache memory, activating a refresh request at the centralized refresh controller in response to generating the RTIM pulse, the refresh request associated with a single cache memory bank of the cache memory, receiving a refresh grant in response to activating the refresh request, and transmitting the refresh grant to a bank controller, the bank controller associated, and localized, at the single cache memory bank of the cache memory.

摘要： Various embodiments of the present invention manage access to a cache memory. In one embodiment, a set of cache bank availability vectors are generated based on a current set of cache access requests currently operating on a set of cache banks and at least a variable busy time of a cache memory includes the set of cache banks. The set of cache bank availability vectors indicate an availability of the set of cache banks. A set of cache access requests for accessing a set of given cache banks within the set of cache banks is received. At least one cache access request in the set of cache access requests is selected to access a given cache bank based on the a cache bank availability vectors associated with the given cache bank and the set of access request parameters associated with the at least one cache access that has been selected.
