    • A pipelined arbitration mechanism allows a routing control decision to be effected for a later packet while a current packet is being transferred. The later packet can be issued a fixed number of cycles after the current request. The mechanism has particular advantages when used with a plurality of functional modules connected to a packet router, whereby a single functional module can generate a current request relating to a current packet and a deferred arbitration request relating to a later packet to be issued a fixed number of cycles after the current request.
    • 流水线仲裁机制允许在当前分组正在传输时对稍后的分组进行路由控制决定。 稍后的数据包可以在当前请求之后发出固定数量的周期。 当与连接到分组路由器的多个功能模块一起使用时,该机制具有特别的优点,由此单个功能模块可以生成与当前分组有关的当前请求以及与要发布固定数量的稍后分组有关的延迟仲裁请求 的当前请求后的周期。

    • A data processing system having shared memory accessible through a transaction-based bus mechanism. A plurality of system components, including a central processor, are coupled to the bus mechanism. The bus mechanism includes a cache coherency transaction within its transaction set. The cache coherency transaction comprises a request issued by one of the system components that is recognized by a cache unit of the central processor as an explicit command to perform a cache coherency operation. The transaction further comprises a response issued by the central processor indicating status of the cache coherency operation.
    • 具有通过基于事务的总线机制可访问的共享存储器的数据处理系统。 包括中央处理器的多个系统组件耦合到总线机构。 总线机制包括其事务集中的高速缓存一致性事务。 高速缓存一致性事务包括由中央处理器的高速缓存单元识别的系统组件之一发出的请求作为执行高速缓存一致性操作的显式命令。 交易还包括由中央处理器发出的指示高速缓存一致性操作的状态的响应。

    • The invention relates to monitoring error conditions in an integrated circuit. The integrated circuit has a packet router to which a plurality of functional modules are connected between which packets are transmitted. Each functional module is associated with an error monitoring register for monitoring error conditions. The error monitoring register contains a plurality of error flags which can be set when a particular error condition is detected. The invention particularly but not exclusively relates to the setting of communication error flags relating to errors in communication of the packet.
    • 本发明涉及监测集成电路中的错误状况。 集成电路具有分组路由器,多个功能模块连接在该分组路由器之间,在其间传送分组。 每个功能模块与用于监视错误状况的错误监控寄存器相关联。 错误监视寄存器包含多个错误标志,当检测到特定的错误条件时可以设置该错误标志。 本发明特别地但不排他地涉及与分组的通信中的错误相关的通信错误标志的设置。
