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： The invention relates to a data processing system and a method for synchronizing data traffic. The data processing system according to the invention comprises a conversion unit, which conversion unit is arranged to convert a first flow control scheme applied in a first sub-network into a second flow control scheme applied in a second sub-network. The conversion unit may cooperate with or be integrated with another component, for example a component which performs conversion of operating frequency between sub-networks (clock-domain crossing). For the correct functioning of flow control it is necessary that separate flow control schemes are used for respectively the first sub-network and the second sub-network. The conversion unit performs a conversion between these schemes. For example, if the flow control schemes are credit-based the conversion unit computes the correct amount of credits for the first flow control scheme, based on the amount of credits available in the second flow control scheme. If necessary, credit conversion is performed. The latter is necessary when the flit sizes are different in the first and second sub-network, for example. The conversion unit translates the credits from the second sub-network (which credits represent a certain amount of data elements) into credits for the first sub-network. The number of credits may be different in respectively the first and second sub-network, for the same amount of data elements.
摘要翻译： 本发明涉及数据处理系统和数据业务同步的方法。 根据本发明的数据处理系统包括转换单元，该转换单元被布置为将在第一子网中应用的第一流控制方案转换为在第二子网中应用的第二流控制方案。 转换单元可以与另一个组件（例如执行子网络之间的工作频率的转换（时钟域交叉））的组件协作或与其集成。 对于流量控制的正确功能，需要分别使用单独的流量控制方案来分别用于第一子网络和第二子网络。 转换单元执行这些方案之间的转换。 例如，如果流量控制方案是基于信用的，则转换单元基于第二流量控制方案中可用的信用量来计算第一流量控制方案的正确的信用量。 如有必要，进行信用转换。 例如，当第一子网和第二子网中的大小不同时，后者是必需的。 转换单元将来自第二子网（其信用表示一定数量的数据元素）的信用转换为第一子网的信用。 对于相同量的数据元素，信用数量在第一和第二子网络中可能分别不同。
