    摘要： In a multiprocessor system buses each coupling a pair of processors (CPU) are serially arranged rectilinearly into a cluster bus arranged in one direction. All of these cluster buses are arranged in a plurality of directions (x, y, z) as a lattice pattern when viewed in plan. Each of the processors (CPU) supplies the respective cluster buses with send requests and priority processing level signals and receives a receipt acknowledge signal from another processor on the same cluster bus, thereby to occupy said cluster bus so as to transfer data to the other processor on the cluster bus.

    摘要： Transmission line groups consisting of a plurality of loop-like transmission routes (1...5, 10...50, 100...500) are mutually connected via transmission controllers and are arranged in a two- or three-dimensional space. Processing units are thus connected as a homogeneous network in matrix or mesh form by means of the loop-like transmission routes The transmission controllers corresponding to the nodes (11...51) of the network have a communication management function such that they send the data without grasping the situation on the transmission routes, independently check the trouble between the adjacent transmission controllers, and specify the position of trouble. A communication network system such as a high local area network (LAN) or the like can be realized.

    摘要： The invention relates to an apparatus for rendering a plurality of sub-data processing systems to a fault tolerant system and a method for majority voting, wherein input signals supplied to the plurality of redundant sub­systems are input to an output selecting circuit after an output of a subsystem is changed from an output signal of a subsystem having a most reliable output signal to an­other output signal of another subsystem having a lower reliable output signal in turn using self-diagnosis and cross-diagnosis in each subsystem according to majority voting rules. The output selecting circuit outputs a sig­nal selected by the majority voting rules based on the output signals from the subsystems.
