TASK SYNCHRONIZATION ARRANGEMENT AND METHOD FOR REMOTE DUPLEX PROCESSORS

摘要

A TASK SYNCHRONIZATION ARRANGEMENT AND METHOD FOR REMOTE DUPLEX PROCESSORS The present arrangement provides for configuration control of a duplex real time processor system without the need for third party configuration control circuitry. A remote control system is connected to duplex real time processors via a pair of serial data links. These data links are configured in an active/standby arrangement. The serial links are connected to the duplex real time processors in such a way that each processor of the pair determines independently whether to assume an active or a standby role. Each real time processor bases this decision upon the identity of the serial link from which it is receiving data transmitted by a remote control system.
