How to programming in ARM processor for SWI, source code example.

ARM汇编实现软中断，用ADS编写。先调用Init装中断，再跳转到SWIhandler，SWIhandler为中断服务程序

ARM处理器软中断处理。a_swi.s文件是最开始处理的SWI句柄,用ARM汇编指令编写。c_swi.c文件是在执行a_swi.s文件之后调用执行的C语言SWI句柄。 -ARM processor soft interrupt handling. a_swi.s document is the beginning of the SWI handler deal with the preparation of ARM compilation directives. c_swi.c document

ARM swi一个简单例子，有兴趣的可以看看，采用keil MDK开发环境编译。- ARM swi a simple example, interested can see, using keil The MDK development of environment to compile.
