    • An electronic signal processing circuit contains a chain of stream processing circuits (12a-d). Linking multiplexing circuits (16a-c), link respective pairs of stream processing circuits (12a-d). Each linking multiplexing circuit (16a-c) is individually switchable to a normal mode and to a replacement mode. A linking multiplexing circuit (16a c), when in the normal mode, provides a continuous connection for passing a first stream of samples values between the stream processing circuits (12a-d) in the respective pair. A shareable communication structure (14a-c) is coupled to the linking multiplexing circuits (I 6a-c). Each linking multiplexing circuit (16a-c), when in the replacement mode, provides a continuous connection for supplying successive sample values from a second stream from the communication structure (14a-c) to a receiving one of the stream processing circuits (12a-d) in the respective pair of the linking multiplexing circuit (16a-c). A control circuit (18) keeps a selectable one of the multiplexing circuits (16a-c) in the replacement mode so that the selectable one of the linking multiplexing circuits (16a-c) passes a stream of successive sample from the second stream to the receiving one of the processing circuits in the respective pair of linking multiplexing circuit (16a-c), while keeping at least part of the other linking multiplexing circuits (I6a-c) in the normal mode.
    • 电子信号处理电路包括一串流处理电路(12a-d)。 链接复用电路(16a-c),链接各对流处理电路(12a-d)。 每个链接多路复用电路(16a-c)可以单独切换到正常模式和替换模式。 当处于正常模式时,链接多路复用电路(16a,c)提供连续的连接,用于在相应的对中的流处理电路(12a-d)之间通过采样值的第一流。 可共享通信结构(14a-c)耦合到链接多路复用电路(I 6 a-c)。 当处于替换模式时,每个链接多路复用电路(16交流)提供连续的连接,用于将连续的采样值从通信结构(14ac)的第二流提供到流处理电路(12Ad)中的接收一个 相应的链路复用电路对(16 ac)。 控制电路(18)将多路复用电路(16 ac)中的可选择的一个保持在替换模式,使得可选择的一个链接多路复用电路(16ac)将连续样本流从第二流传递到接收一个 在相应的一对链接多路复用电路(16交流)中的处理电路,同时保持其他链接多路复用电路(I 6 ac)的至少一部分处于正常模式。

    • An integrated data processing circuit contains matrix of programmable processors. Each processor (12) has private operand transfer connections to its neighboring processors (12) in the matrix, typically for passing operands of transfer commands. An additional tree communication structure contain router circuits (16, 18, 19) hierarchically coupled to each other and to the processors. The processors (12) form leave nodes of the tree structure, the router circuits (16, 18, 19) being arranged to route a message with an address from a root router (19) circuit to an addressed processor (12), selectively via a path through the tree structure, the router circuits (16, 18, 19) each selecting a part of the path under control of the address.
