Computer architecture based on a multimicroprocessor structure as a fail-tolerant system

摘要

The present invention is based on the object of creating a computer architecture which ensures fault-tolerant operation. The failure of a component or fault in a component of the overall system do not lead to the failure of the overall system. Defined stand-by elements which are only used when needed, or duplicated elements which are only used for carrying out specific tasks in parallel, are not provided in the computer architecture according to the invention. The exception to this are the interface devices provided at the interfaces between the computer architecture and the peripheral or the computer architecture and the user level. The object is achieved by a ring-shaped partly-meshed arrangement of microcomputers, in which each microcomputer monitors the functions of the microcomputer adjacent to it in the ring. In principle, every microcomputer can take over the tasks of all other microcomputers. IMAGE
