　　Abstract The embedded system hardware development requests the designer to be extremely familiar to the hardware resources, And can aim at in the project the concrete application, the overall evaluation system demand, the performance index, the cost and so on the various factor, carries on the overall plan, thus obtains had under the condition preferred plan. This embedded system design involves specifically to the CPU shaping and the memory, Flash and the periphery connection indeed grades content.

　　1 微处理器的选择

　　所有硬件选择中，最关键的就是嵌入式处理器的定型，因为它决定了整个系统的基本性能和其他外围硬件的选用。
