摘　　要：随着现代科学技术的不断发展,对ARM微处理器的研究也不断的发展。本文对微处理器的中断响应时间进行了实验研究,对ARM微处理器S3C2440A的中断处理机制进行分析,并在此基础上设计了一种实验测定中断响应时间的方法,从而对在理想状态下S3C2440A的快速中断FIQ和标准中断IRQ的响应时间做出了对比,对其实验数据在分析处理之后,进行了模拟函数的研究。With the continuous development of modern science and technology,the research on ARM microprocessor has also been developed continuously,which needs to be studied experimentally in the interrupt response time of the microprocessor. In this paper,the interruption processing mechanism of the ARM microprocessor S3 C2440 A is analyzed. On this basis,a method of testing the interrupt response time is designed,and the response time of the fast interrupt FIQ and the standard interrupt IRQ in the ideal state is compared,and the experimental data are in the case of the S3 C2440 A. After analyzing and processing,the simulation function is studied.
