A Co-processing Method Based on Warm Standby Systems

Dual-computer warm standby redundant architecture is one of the most commonly used architectures in redundant fault tolerance. Using this architecture, the computing results of the backup computer is unused when it has no power although the backup computer is keep running that is a waste of computing resource of the backup computer. This paper proposes a co-processing method which makes rational use of computing resource by taking advantage of the communication unit, and increases the output frequency of the system's optimized module. The test results show that this method improves the performance of the system with the assurance of the reliability.
