Abstract: A processor control system for controlling items of hardware includes pairs of processors associated with the hardware items. One processor of each pair operates the process or processes for controlling the associated hardware, while the other processor of each pair operates other processes. In the event of a fault in one processor the processes on that processor are transferred to spare processors and the hardware control process is transferred to the other processor of the pair. This arrangement makes more effective use of standby processing capacity.

- 17 May 1985
TL;DR: In this article, a duel processor system (100) with duplicated memory (114,124) has two modes (10,11) of operation: a converged mode in which one of the two processors (101,102) is active and executing all system tasks while the other processor is inactive; and a diverged mode (11) in which both processors are active and independently executing different tasks.

Double redundant processor
John C. McDonald,James R. Baichtal +1 more
- 12 Apr 1979
TL;DR: In this paper, a double redundant processor including first and second master processors for processing data, control and address signals in a data processing system is described. But the first master processor is in an active state for processing the signals and the second master processor, in a standby state, is in a non-active state.
