摘要
针对复杂重要系统实时性及可靠性要求,提出了一种单片机双CPU控制系统。介绍了系统的设计思想、报警系统,叙述了系统中双CPU间独特的仲裁切换、故障的自我检测及同步控制等,并从软件方面给出一个应用双CPU系统的设计实例。
This paper presents a type of dual CPU system of chip microcomputer based on the requirements of real-time performance and reliability for some complex-important system, introduces the design concept and the warning system of this system, expounds the unique arbitrary switch-over between the two CPUs, the self-detection for the faults, and synchronous control, etc., and gives an example applied the dual CPU system in aspect of the software.
