摘要： An apparatus for controlling access to a pipeline includes a plurality of command queues including a first subset of the plurality of command queues being assigned processes the commands of first command type, a second subset of the plurality of command queues being assigned to process commands of the second command type, and a third subset of the plurality of the command queues not being assigned to either the first subset or the second subset. The apparatus also includes an input controller configured to receive requests having the first command type and the second command type and assign requests having the first command type to command queues in the first subset until all command queues in the first subset are filled and then assign requests having the first command type to command queues in the third subset.

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 memory system, apparatus and method for performing operations in a shared cache coupled to a first requester and a second requester. The method includes receiving at the shared cache a first request from the second requester; assigning the request to a state machine; transmitting a first pipe pass request from the state machine to an arbiter; providing a first instruction from the first pipe pass request to a cache pipeline, the first instruction causing a first pipe pass; and providing a second pipe pass request to the arbiter before the first pipe pass is completed. The first requester may be a lower level cache such as an L2 cache, or an I/O device and the second requester may be an upper level cache such as an L4 cache, and the first request may be a coherency request.

摘要： A cache includes a cache pipeline, a request receiver configured to receive off chip coherency requests from an off chip cache and a plurality of state machines coupled to the request receiver. The cache also includes an arbiter coupled between the plurality of state machines and the cache pipe line and is configured to give priority to off chip coherency requests as well as a counter configured to count the number of coherency requests sent from the cache pipeline to a lower level cache. The cache pipeline is halted from sending coherency requests when the counter exceeds a predetermined limit.

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.
