| Abstract: | The paper analyzed basic principle of anti-interference technology of software of Single-chip microcomputer system.It discusses the basic method by which the wrong program can be pulled back to right track by changing the value of program counter.It can improved the anti-interference capability in the way of software.Based on this theory,the paper proposed software method which can improve the stability of the Single-chip microcomputer system,such as order redundanle,software traps、software detection,and presented practical example in detail and the program chart. |
