| 摘 要： | 近年来，嵌入式系统成为计算机领域发展最迅速的方向之一。中断的设计和实现是嵌入式系统设计的关键部分。结合ARM S3C4510B开发板，介绍了中断向量表的配置和中断的实现流程，并根据中断处理的特点提出一种中断改进的方案。这种方案克服传统处理过程不支持中断向量表动态修改的缺点，提高了程序的可移植性。

| Abstract: | In recent years,embedded system becomes one of the most popular directions in the computer.Design and implementation of interrupt has become a key part of embedded system design.Based on the S3C4510B,configuration of interrupt vector table and im-plementation flow of interrupt are introduced.According to the characteristic of the management of interrupt,a way to improve disposal ofinterruptis given.The traditionalway's disadvantage that can't amend interrupt vector table dynamically isovercome,and the transplant of program is improved. |
