dds

一个2位的BCD码十进制加法计数器电路，输入为时钟信号CLK，进位 输入信号CIN，每个BCD码十进制加法计数器的输出信号为D、C、B、A和进位输出信号COUT，输入时钟信号CLK用固定时钟，进位输入信号CIN. (A 2-bit BCD code decimal adder counter circuit input as the clock signal CLK, a carry input signal CIN, D, C, B, A, and the carry output signal COUT, each BCD code decimal adder counter' s output signal, the input clock signal CLK Fixed clock, binary input signal CIN.)

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,图像形态学部分,腐蚀,膨胀,细化算法(System Generator based image processing engineering, multimedia processing FPGA implementation source code, image morphology section, corrosion, swelling, thinning algorithm)

处理单元的 risc_spm 你可以求出其存储的程序对某些容易操作。

说明：  USB传图至fpga板缓存至DDR内，FPGA再读出图像数据，显示在TFT彩屏上；(USB to the FPGA board cache DDR, FPGA read out the image data, display on the TFT color screen;)

基于fpga状态机的交通灯设计，亮灯时间自己修改，程序简单易懂。(Traffic light design based on FPGA state machine, light time self-modifying, the program is simple and easy to understand.)

说明：  RISC 5级流水线CPU，带HAZARD处理(RISC 5 pipeline CPU with HAZARD processing)

使用DE2实现DDS，步骤简单，配置管脚可自查看(Using DE2 to realize DDS, the steps are simple and the pins can be self-checked.)

Arbiter code for simulation purpose

用Verilog代码来实现iic协议，主要是通过两个按键来控制读写命令，读取的数据最后用数码管显示出来，代码里面有很详细的注释和说明。
