从系统设计角度上提高机器的可靠性、可用性,可维修性这一综合技术已广泛用在大型计算机系统中。1001机是一台中型多功能通用数字计算机,要求结构简单、元件省、稳定可靠。在上述前提下,我们只在可校正技术方面做了一些尝试,取得了较好的效果。 在以往的机器中,广泛采用奇偶校验的方法来校验主存读出信息的正确性,若读出信息奇偶错则进入中断处理,这种方法有一定的局限性,它只能发现奇数位出错且不能纠正。因此校验效果不够理想。根据统计表明,主存贮器一位出错的概率占整个主存贮器出错的80~90%,
From the system design point of view to improve the reliability of the machine, availability, maintainability of this comprehensive technology has been widely used in large computer systems. 1001 machine is a medium-sized multi-purpose general-purpose digital computer, requiring a simple structure, saving components, stable and reliable. Under the above premise, we have only made some attempts to correct the technology and achieved good results. In the past machines, the parity check method is widely used to check the correctness of the main memory read information. If the parity of the information is read, the interrupt processing is performed. This method has some limitations. It can only find odd numbers Bit error and can not be corrected. Therefore, the verification effect is not ideal. According to statistics, the main memory of an error probability of the entire main memory error of 80 to 90%
