摘要
微机系统,包括微机化仪器与控制装置受到干扰后往往会出现系统“锁死”而无法正常工作的严重后果。预防这种现象,或者已经出现这种现象而使其恢复正常的运行状态,在硬件与软件两方面均可采取一些措施。本文专门讨论软件方面所采用的一些办法。
The various distrubances often take place in a microprocessor system, and make the system, fail to work. There are many methods to overcome these weaknesses by the software and hardware. This paper only describes some software approaches. The discussion includes introduction, programming, trap and watchdog et cetera. The final section summarizes some thinking to take note of the program design.
