Abstract
Method for the operation of a multiprocessor controller, at least some of the processors (BP, CP, IOC, IOP) having access via first switches (S) and thus via each half (B:CMY0, B:CMY1) of a central inherently duplicated bus system (B:CMY) and second switches (SW) connected thereto to each half of an inherently duplicated main memory (CMY), or to each half (e.g. MB3a or MB3b) of one or more inherently duplicated memory banks (MB) of the main memory (CMY). In a special operating time, a redundant part of the controller is separated and interconnected to form a small, discrete, independently operating special processor by interconnecting individual redundant processors of this group (e.g. CP9 and/or IOC1) to one half (e.g. B:CMY1) of the bus system (B:CMY) and to a part of the main memory (CMY) or the memory banks (MB) in order to form an independent special processor for a special program, and continuing to run the so far normally operating program in the remaining parts of the controller, that is to say in the residual processor. The special processor later interrupts its special program. The components of the special processor are reconnected to the residual processor in such a way that only the normal operating program or a newly input modification thereof runs. <IMAGE>
