Interrupt response is an important index to measure the embedded operating system, and the high efficiency interrupt handling mechanism can greatly improve the system's interrupt response. In this paper, we analyze interrupt processing flow of MQX Lite, and propose a fast interrupt mechanism ,in which Emergency handling is embedded in the kernel ISR. The interrupt response time of three interrupt handling points including kernel interrupt, user terminal and user task in the fast interrupt mechanism is detected, and the experimental data show that the mechanism can significantly improve the system's interrupt response, and can meet the high risk of high voltage, explosion-proof, and other high risk applications.
