摘要： A communication system. One embodiment includes at least two functional blocks, wherein an first functional block communicates with a second functional block by establishing a connection. A connection is a logical state in which data may pass between the first functional block and the second functional block. One embodiment includes a bus coupled to each of the functional blocks and configured to carry a plurality of signals. The plurality of signals includes a thread identifier that indicates a transaction stream that the data transfer is part of and a busy signal identified by the thread identifier. The busy signal is issued by the target functional block when resources will be unavailable to perform a transfer.

摘要： A system and method for providing service guarantees for data flows between an initiator component and a target component. For each data flow, a set of channels is selected to carry the data flow from initiator to target. The individual performance guarantees of the selected channels are aligned to be uniform in units and the individual guarantees are aggregated to provide an end-to-end service guarantee for a particular flow.

摘要： Embodiments of apparatuses, systems, and methods are described for a machine-readable medium having instructions stored thereon, which, when executed by a machine, to cause the machine to generate a representation of an apparatus. The apparatus includes a bridge agent, a first interconnect, and a second interconnect. The bridge agent is configured by bridge control signals to control transmission of a communication between the first interconnect and the second interconnect. The representation may be a sequence of instructions written in a programming language to mimic in a computer simulation environment attributes derived from a projected fabricated hardware instance of the apparatus.

摘要： In general, methods and apparatus for implementing a Quality of Service (QoS) model are disclosed. A Quality of Service (QoS) contract with an initiating network device may be satisfied. A request may be received from the initiating network device in a first time less than or equal to an ordinal number times an arrival interval. The ordinal number signifies a position of the request among a group of requests. The request that has been serviced may be returned to the initiator in a second time less than or equal to a constant term plus the ordinal number times a service interval.

摘要： Various methods and apparatuses of protection mechanism are described. A target intellectual property block may field and service requests from an initiator intellectual property block in a system-on-chip network. The target intellectual property block has an associated protection mechanism with logic configured to restrict access for the requests to the target intellectual property block. The request's access is restricted based on access permissions associated with a region within the target intellectual property block and attributes of the request trying to access that region.

摘要： Various methods and apparatuses are described in which an interconnect couples to a plurality of initiator network resources and a plurality of target network resources. The interconnect may include a first stage of circuitry, a second stage of circuitry, and an arbitration controller. The first stage of circuitry receives incoming transactions from the plurality of initiator network resources. The second stage of circuitry passes outgoing transactions to the plurality of target network resources connecting to the interconnect. The arbitration controller arbitrates transactions from the plurality of initiator network resources destined to one or more of the target network resources. The target network resources supply their availability to service a transaction to the arbitration controller. The arbitration controller implements an arbitration policy that filters out transactions from the arbitration process those transactions from initiator network resources destine to target network resources that are currently not available to service a transaction.
