首先，分析TMS320F240 DSP芯片的中断系统结构，包括其内核中断、事件管理模块的中断和系统模块中断。然后，分析DSP中断的处理过程和中断程序的编制方法。最后，给出中断系统的C语言编程方法。

-Firstly, TMS320F240 DSP chip interrupt system structure, including its core interrupt, event management module interrupts and interrupt system modules. Then, the preparation method of analysis processing DSP interrupts and interrupt routine. Finally, the system interrupts the C programming language.
