DAC verilog 的 Termometric 代码

Commponent for drivering EEPROM memory AT25320 from Avalon bus.

里面含有vhdl和verilog 版本,很好用!dct变换用得很多啊!(Which contains a VHDL and Verilog versions of very good use! Dct transform with a lot ah!)

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

本实验是利用Verilog来驱动PS2，读取键盘的字母，并在lCD上显示。 本代码中只设置对键盘的字母进行检测，而对其他的没有检测。

用verilog编写的信号调制解调程序，包括ask,fsk,qpsk的fpga实现(Prepared using verilog signal modulation and demodulation process, including ask, fsk, qpsk of fpga implementation)

实现多周期mips  设计一个32位MIPS多周期微处理器 具有多种 算数指令： (Design a 32-bit MIPS microprocessor multi-cycle arithmetic instructions

FPGA的测频程序，用了D触发器，能测1hz到几百hz(FPGA frequency measurement procedures, using a D flip-flop, can be measured to a few hundred hz 1hz)

fpga控制da产生幅值频率可调的正弦波程序(the fpga Control da produce the amplitude adjustable frequency sine wave program)

ov5620在FPGA中的使用，本程序实现的功能是驱动摄像头OV5620，并将数据通过VGA接口输出，外接显示器即 看到摄像头的图像。
