这是有关cpu和存储器挂接的一个硬件课程设计，图片是用protel 99 se 画的，程序用唐都仪器调试通过，仅为一个理论性的东西。自己写的，请多指教。--It is a class written by me, which describes cpu and rom hardware design. The picture is drawn by protel 99 se. The program is passed on Tang Du instrument.

This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO. -This model is just an idea of testing MIMO. IEEE802.11n which will have. But I havo not seen the standard.

应用背景 所有红外遥控器的输出都是用编码后串行数据对38～40kHz的方波进行脉冲幅度调制而产生的。如果直接对已调波进行测量，由于单片机的指令周期是微秒（μs）级，而已调波的脉宽只有20多μs，会产生很大的误差。因此先要对已调波进行解调，对解调后的波形进行测量。红外遥控接收芯片CX20106可以完成对遥控信号的前置放大、限幅放大、带通滤波、峰值检波和波形整形，只需加上简单的外围电路即可完成对已调波的解调 关键技术 用红外转发器控制电器，首先要进行对码，把要控制的家电遥控器对准红外转发器，把遥控器的功能键学习到红外转发器中，学习成功后，就可以控制了，例如，学习了空调遥控器的开、关，用POLYHOME智能主机操作空调开，主机发出射频信号到红外转发器，红外转发器把射频信号转成红外信号的“开”发射出去，就能把空调打开了，射频可以穿墙，红外信号是不能穿墙的，这就能实现远距离控制电器。

flash测试代码，它主要是针对SST39VF1601进行测试，主控制器是44B0。-flash test code, it is mainly directed against SST39VF1601 test, the main controller is 44B0.

用VC++6.0与单片机通过RS232通信程序，上位机程序主要是控制单片机发出一些指令，单片机上传一些数据到上位机，上位机通过这些数据作出决策，再发送指令到单片机。-With VC++ 6.0 and MCU through RS232 communication procedures, procedures for the main PC to control a number of directives issued by single-chip microcomputer, microcontroller upload some data to the host computer, host computer through the data to make decisions, and then send commands to the Singlechip.
