虽然使用8051可以在C语言程序中嵌入汇编代码，但是复杂度明显提高。

Though 8051 could embed assembly code at C-language programming, the complicity is obviously improved.

这个编译器也允许在一个函数的任何地方嵌入内联的汇编代码。另外，以汇编代码开发的例程也可以被调用。

The compiler also allows inline assembler code to be embedded anywhere in a function. In addition, routines developed in assembly can also be called.

另外，笔者的试验平台建立在ARM系列的嵌入式芯片基础上，所以不少地方引用了ARM汇编代码，限于篇幅，请另行参阅arm参考资料。

Otherwise, my experimental platform is based on ARM series embedded chips, so I used a lot of ARM assembler codes. Please read other ARM reference for more information.
