Device for fault-tolerant execution of programs

摘要

The device is used for fault-tolerant execution of programs, and is particularly suitable for execution of digital computer programs. The device has several computing units, which are connected to a control unit, which operates the computing units in parallel, to provide fault tolerance. Each of the computing units is in the form of a redundancy unit, and is connected via an interface to a data bus with three-fold redundancy. Redundant process peripherals are connected to the data bus. Each computing unit consists of at least one transputer node. To implement redundancy corresponding to Byzantine fault tolerance in circuit form, a redundancy group is formed from at least four computing units. Each computing unit within a redundancy group is connected to at least three further computing units.
