A State Transition Model for Anti-Interference on the Embedded System

Microprogrammed Control Unit (MCU) and embedded systems are widely used in all kinds of industrial, communication devices and household appliances. However, for the embedded system, even with well hardware protection, the stability are often impacted by the complicated Electro Magnetic Interference (EMI) and the others interference. To get a better system stability ratio, this paper introduces a potent state transition model for the anti-interference intention instead of the empiristic methods. The states of the embedded system are classified into three types: I/O, Computing, and Error. By the state transition diagram, we deduced a set of anti-interference probability model, which guide the software measures for the anti-interference intention and reduce the unstable probability of the embedded system.
