Comparison of two "software trap techniques" [Copy link]

The anti-interference of single-chip microcomputer application systems can be specifically divided into two aspects: software and hardware. Among them, software anti-interference is increasingly widely adopted due to its advantages such as flexible design, saving hardware resources and reducing costs. Software anti-interference technologies mainly include "instruction redundancy technology", "software trap technology", "software watchdog technology", "digital filtering technology" and so on. This paper discusses and studies the principle and specific implementation method of software trap technology for anti-interference of single-chip microcomputer application systems, gives two forms of implementing software trap technology, and successfully uses this technology in multiple actual single-chip microcomputer application systems to ensure the reliable operation of the system.
