    摘要： An improved method and apparatus for resource arbitration. Four priority classes, managed high (MH), managed low (ML), opportunistic high (OH) and opportunistic low (OL), are defined. A priority class is assigned to each resource access request. An access request concentrator (ARC) is created for each resource, through which the resource is accessed. An access request is chosen at each ARC using the priority order MH, ML, OH, and OL, in decreasing order of priority. If OH priority class resource access requests are locked out, the priority order is temporarily changed to OH, OL, MH, and ML, in decreasing order of priority. If OL priority class resource access requests are locked out, the priority order is temporarily changed to MH, OL, OH, and ML, in decreasing order of priority.

    摘要： In a first aspect, a first method of reducing command processing latency while maintaining memory coherence is provided. The first method includes the steps of (1) providing a memory map including memory addresses available to a system; and (2) arranging the memory addresses into a plurality of groups. At least one of the groups does not require the system, in response to a command that requires access to a memory address in the group from a bus unit, to get permission from all remaining bus units included in the system to maintain memory coherence. Numerous other aspects are provided.

    摘要： A method for maintaining cache coherency for a multi-node system using a specialized bridge which allows for fewer forward progress dependencies. A local node makes a determination whether a request is a local or system request. If the request is a local request, a look-up of a directory in the local node is performed. If an entry in the directory of the local node indicates that data in the request does not have a remote owner and that the request does not have a remote destination, the coherency of the data is resolved on the local node, and a transfer of the data specified in the request is performed if required and if the request is a local request. If the entry indicates that the data has a remote owner or that the request has a remote destination, the request is forwarded to all remote nodes in the multi-node system.

    摘要： A system and method for flexible multiple protocols are presented. A device's logical layer may be dynamically configured on a per interface basis to communicate with external devices in a coherent or a non-coherent mode. In coherent mode, commands such as coherency protocol, system commands, and snoop response pass from the device's internal system bus to an external device, thereby creating a logical extension of the devices internal system bus. In non-coherent mode, the input-output bus unit receives commands from the internal system bus and generates non-coherent input-output commands, which are eventually received by an external device.

    摘要： A method and apparatus are provided for implementing data mapping using a shuffle algorithm. An output shuffler and an input shuffler convert a physical data group to a plurality of data subgroups. The physical data group includes a plurality of bits and each subgroup includes a subplurality of bits. The output shuffler performs an output shuffle sequence for providing a predefined output pattern of ordered subplurality data bits. The predefined output pattern of ordered subplurality data bits is applied to the input shuffler. The input shuffler performs a reverse shuffle sequence. For each shuffle transfer a number of first header bytes of a packet are located at a first one of a plurality of physical layer links. Both the output shuffler and the input shuffler are implemented with minimized logic required to keep a largest multiplexer as a 4-to-1 multiplexer, resulting in minimal area and power being used for implementing the shuffle sequence and reverse shuffle sequence.
