    • A router circuit (130) is made configurable as either a crossbar switch or a hyperbar switch by dividing the router chip into sections (sections A-D), where each section is associated with a group of input terminals, and wherein various grant circuits (272) within each of the sections have enable/disable input terminals (506) connected by controllable switches (400) to either enable/disable output terminals of grant circuits in an adjacent section (hyperbar personaly) or to fixed logic levels (crossbar personality). In the crossbar configuration, for each input terminal of a section, only one grant circuit (272) per channel is enabled. Each of the sections has a different set of grant circuits enabled per channel so that two sections can not access a same output terminal of the router chip. In the hyperbar configuration, the sections are made transparent, and grant circuits are enabled or disabled depending on output wire availability. Additionally, the router circuit contains novel routing address bit and protocol bit circuitry (252, 258) as well as novel diagnostic circuitry (584) for detecting broken wires (550) between router circuits.
    • 通过将路由器芯片分成部分(部分AD),每个部分与一组输入终端相关联,路由器电路(130)可配置为交叉开关或超级开关,并且其中各种授权电路(272) 在每个部分内,具有通过可控开关(400)连接的启用/禁用输入端子(506),以使得/禁用相邻部分(超级棒人)中的授权电路的输出端或者固定逻辑电平(交叉开关人格)。 在交叉开关配置中,对于每个输入端子,每个通道仅允许一个授权电路(272)。 每个部分具有每个通道启用的不同的授权电路集合,使得两个部分不能访问路由器芯片的相同输出端子。 在超高速配置中,这些部分是透明的,并且根据输出线路可用性启用或禁用授权电路。 此外,路由器电路包含新颖的路由地址位和协议位电路(252,258)以及用于检测路由器电路之间的断线(550)的新型诊断电路(584)。

    • An object is to provide an information processing apparatus capable of improving the availability as a system while improving the reliability of a data transfer path and a data transfer method. An information processing apparatus has a data transfer path branching in a tree structure, from a root node to a plurality of nodes while communicably coupling therebetween and transmitting serial data between the root node and the plurality of nodes, including two internode data transfer paths provided between at least a pair of nodes of the plurality of nodes, through which serial data transfer is performed; and a routing processing unit provided to each terminal nodes that are the nodes on both ends of the internode data transfer path, transfers the return data from the transmission destination node to the transmission source node by using the same internode data transfer path as the internode data transfer path used for data transfer to the transmission destination node, when each of the terminal nodes transfers data received from any of another nodes being a transmission source to any of the nodes being a transmission destination via the other terminal node.
    • 本发明的目的是提供一种在提高数据传送路径和数据传送方法的可靠性的同时提高作为系统的可用性的信息处理装置。 信息处理装置具有以树结构分支的数据传输路径,从根节点到多个节点,同时可通信地耦合它们之间并在根节点和多个节点之间传送串行数据,包括两个节间数据传输路径, 所述多个节点中的至少一对节点通过其进行串行数据传送; 以及路径处理单元,被提供给作为节间数据传送路径的两端的节点的每个终端节点,通过使用与节间数据相同的节间数据传送路径将返回数据从发送目的地节点传送到发送源节点 当每个终端节点通过另一个终端节点将从作为发送源的另一个节点中的任一个接收的数据传送到作为发送目的地的任何节点时,用于数据传送到发送目的地节点的传送路径。
