摘要： A communication infrastructure for a data processing apparatus, and a method of operation of such a communication infrastructure are provided. The communication infrastructure provides first and second switching circuits interconnected via a bidirectional link. Both of the switching circuits employ a multi-channel communication protocol, such that for each transaction a communication path is established from an initiating master interface to a target slave interface, with that communication path comprising m channels. The m channels comprise one or more forward channels from the initiating master interface to the target slave interface and one or more reverse channels from the target slave interface to the initiating master interface, and handshaking signals are associated with each of the m channels. The bidirectional link comprises n connection lines, where n is less than m, the bidirectional link supporting a first communication path from the first switching circuit to the second switching circuit and a second communication path in an opposite direction from the second switching circuit to the first switching circuit. Control circuitry is used to multiplex at least one forward channel of the first communication path and at least one reverse channel of the second communication path, with the multiplexing being performed in dependence on the handshaking signals associated with the channels to be multiplexed. This allows the 2m channels formed by the first and second communication paths to be provided by the n connection lines of the bidirectional link.

摘要： A data processing apparatus and method are providing for arbitrating access to a shared resource. The data processing apparatus has a plurality of logic elements sharing access to the shared resource, and arbitration circuitry which is responsive to requests by one or more of the logic elements for access to the shared resource to perform a priority determination operation to select one of the requests as a winning request. The arbitration circuitry applies an arbitration policy to associate priorities with each logic element, the arbitration policy comprising multiple priority groups, each priority group having a different priority and containing at least one of the logic elements. Within each priority group, the arbitration circuitry applies a priority ordering operation to attribute relative priorities to the logic elements within that priority group. Responsive to a predetermined event, the arbitration circuitry re-applies the priority ordering operation within at least one priority group prior to a subsequent performance of the priority determination operation. Such an approach has been found to provide a particularly flexible mechanism for performing arbitration, allowing a wide variety of different arbitration schemes to be implemented using the same arbitration hardware.

摘要： Arbitration circuitry is provided to select an output from between multiple inputs each having an associated priority value. A tie-break value is appended to the least significant bits of each of the priority values to form extended priority values before those extended priority values are compared. Thus, if two priority values are equal, then the appended tie-break bits are used to determine which of the two inputs will be selected as having the higher priority.
摘要翻译：提供仲裁电路以从多个输入之间选择输出，每个输入具有相关联的优先级值。在每个优先级值的最低有效位之后追加中断值，以在比较扩展优先级值之前形成扩展优先级值。因此，如果两个优先级值相等，则附加的中断位用于确定两个输入中的哪一个将被选择为具有较高优先级。

摘要： A data processing apparatus includes a first component for generating a signal operating in the first clock domain having a first clock period, and a second component for receiving the signal operating in the second clock domain having a second clock period. The second clock period is synchronous with but slower than the first clock period. Interface circuitry is provided for translating the signal between the first clock domain and the second clock domain, the interface circuitry operating in the first clock domain and comprising a storage element for temporarily buffering the signal generated by the first component before outputting that signal to the second component. Enable circuitry is used to control output of the signal from the storage element having regard to a specified input delay value identifying an input delay time of the second component expressed in terms of the first clock period.
