摘要： A method for exchanging data between first and second functional units includes the following steps. In a first handshake procedure, data is exchanged corresponding to a communication thread selected by the first functional unit, while independently in a second handshake procedure, information relating to a status of at least one communication thread is exchanged from the second to the first functional unit. The information enables the first functional unit to anticipate the possibility of exchanging data for the at least one communication thread.

摘要： A data processing system and a method for synchronizing data traffic including a conversion unit which converts first data into second data. The first data is controlled by a first scheme for reservation of resources and the second data being controlled by a second scheme for reservation of resources. The conversion unit may be referred to as a network-level bridge (NWB) . For example, the different schemes for reservation of resources may be based on slot tables, in which case, the conversion unit converts the slot assignments for the first data into the slot assignments for the second data.

摘要： An integrated circuit includes processing modules and an interconnect device for coupling the processing modules and for enabling a device-level communication based on transactions between the processing modules. A first processing module issues a transaction towards a second processing module. The integrated circuit further includes a transaction abortion unit for aborting the transaction issued from the first module by receiving an abort request issued by the first module, by initiating a discard of the transaction to be aborted, and by issuing a response indicating the success/failure of the requested transaction abortion.

摘要： The invention relates to an integrated circuit and to a method of arbitration in a network on an integrated circuit. According to the invention, a method of arbitration in a network on an integrated circuit is provided, the network comprising a router unit, the router unit comprising a first input port, a second input port and an output port, wherein the router unit receives at least one first packet via the first input port, and wherein the router unit receives at least one second packet via the second input port, the router unit arbitrating between the first packet and the second packet, characterized in that the step of arbitrating is performed using a first label and a second label, the first label being attached to the first packet, and the second label being attached to the second packet. This method relies on the perception that the arbitration performed by a router should be based on connection arbitration instead of input port arbitration. This means that instead of merely arbitrating between the contending input ports in a router, the arbitration should also take into account the connections to which packets correspond. This can be done by attaching labels to the packets, which labels are used in the arbitration process. In this way, it is possible to achieve a fair allocation of bandwidth to different connections, regardless of on which input ports these connections are established.
摘要翻译： 本发明涉及集成电路和集成电路中的网络中的仲裁方法。 根据本发明，提供了一种在集成电路中的网络中仲裁的方法，所述网络包括路由器单元，所述路由器单元包括第一输入端口，第二输入端口和输出端口，其中所述路由器单元接收 至少一个第一分组经由所述第一输入端口，并且其中所述路由器单元经由所述第二输入端口接收至少一个第二分组，所述路由器单元在所述第一分组与所述第二分组之间进行仲裁，其特征在于，所述仲裁步骤使用 第一标签和第二标签，第一标签被附加到第一分组，第二标签被附加到第二分组。 该方法依赖于路由器执行的仲裁应基于连接仲裁而不是输入端口仲裁的认知。 这意味着，仲裁还应考虑到数据包对应的连接，而不是在路由器中的竞争输入端口之间进行仲裁。 这可以通过将标签附加到分组来完成，这些标签在仲裁过程中被使用。 以这种方式，无论在哪些输入端口上建立这些连接，都可以实现对不同连接的公平分配带宽。

摘要： An integrated circuit comprising a plurality of processing modules (M; I; S; T) and a network (N; RN) arranged for providing at least one connection between a first and at least one second module is provided. Said connections comprises a set of communication channels each having a set of connection properties. Said connection supports transactions comprising outgoing messages from the first module to the second module and return messages from the second module to the first module. The connection properties of the different communication channels of said connection can be adjusted independently. Therefore, the utilization of the resources of a network on chip is more efficient, since the connection between modules can be efficiently adapted to their actual requirement, such that the connection is not over dimensioned and unused network resources can be assigned to other connections.
