software interruption

Since the item make onboard computer system as background, software fault injection system simulation platform SFIS is built, and interruption method is adopted to inject faults into the system.

由于本研究课题是以星载计算机系统为背景，所以本文建立了软件故障注入系统仿真平台SFIS，采取中断的方法对目标系统进行软件故障注入。

Software designed divide into three model: initialize , serial interruption service programming, serial port selected.

软件设计分为: 初始化、串行中断服务程序 、 串行口选择三个模块.

The software includes the system control program and the analysis program on PC. The system control program consists of the main procedure, initialization module, timer interruption module, data processing module, alarm module, serial communication module and storage module.

软件包括单片机软件和PC机分析软件。单片机软件由主程序、初始化模块、定时器中断模块、数据处理模块、报警模块、串口通信模块和存储模块组成。

Based on the principle of Software Replacing Hardware, this paper presents a new method to display different data on digital code scope with the harmonious use of timer and external interruption, and the normal control operation of CPU will not be negatively affected.

本文从以软代硬的原则出发，给出一种利用定时器和外中断的协同使用，在数码管显示器上分时显示不同数据，而不影响CPU的正常控制动作。
