嵌入式编程精华，总结了几乎所有的提供效率的编程方法，很有价值-good for embedded program

这是一个用Verilog编写的简单的处理器，虽然只有5条指令，通过这个例子，了解cpu架构，如何开发处理器，会很有启发性。

嵌入式处理器arm的启动代码，使用范围较广-Embedded processor arm of the startup code, the use of a wider scope

利用DSP的MCBSP串口调用其内部正弦表 重串口输出正弦-use DSP MCBSP serial called its internal sine table re-Serial output sinusoidal

裡面有兩隻程式， 一個可以用於改變一個單位的任何一個bit的01，另一隻可以驗證其01是否有真正被更改， 我是將其數字直接算成二進位的樣子輸出. 個人覺得挺好用的， 希望大家會喜歡

CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模，加减时不进，错位，如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.
