    • A crossbar routing arrangement is disclosed for use in a digital system having three or more buses. An associated method is also disclosed. The routing arrangement is configured for transferring a set of data received from any particular one of the buses to any other selected one of the buses and includes a control arrangement associated with each bus for dividing the set of data into at least first and second subsets of data and for adding self-routing signals to each data subset which signals identify the selected bus. A switching arrangement is configured for directing the first and second data subsets in a predetermined way responsive to the self-routing signals. The control arrangement cooperates with the switching arrangement to transfer the data subsets over physically distinct data transfer paths defined between the switching arrangement and the control arrangements. In accordance with one feature, the configuration of the routing arrangement provides for linear expansion whereby to service buses having increased width and/or to service an increased number of buses in a cost effective manner while, in either instance, maintaining high data throughput.
    • 公开了一种用于具有三个或更多个总线的数字系统中的横梁路由布置。 还公开了一种相关联的方法。 路由布置被配置为将从总线中的任何特定一个总线接收的一组数据传送到总线中的任何其他所选择的总线,并且包括与每个总线相关联的控制装置,用于将该组数据分成至少第一和第二子集 数据和用于将每个数据子集添加自路由信号,信号标识所选择的总线。 交换装置被配置为响应于自路由信号以预定方式引导第一和第二数据子集。 控制装置与切换装置配合以将数据子集传送到在切换装置和控制装置之间限定的物理不同的数据传输路径上。 根据一个特征,路由布置的配置提供线性扩展,从而以成本有效的方式服务具有增加的宽度和/或服务于增加数量的总线的总线,而在任一情况下维持高数据吞吐量。
