数码管时钟

UART communication on SPARTAN 6 it contains tx and rx

说明：  此程序用来实现图像的采集和帧数的计算功能。(Image acquisition and calculation of the number of frames.)

xilinx FPGA设计需要的DDR2文件，可以应用于实际设计中(xilinx FPGA design needs DDR2 files that can be applied to the actual design)

使用matlab实现cdma 系统的rake接收机，比较最大比合并，等增益合并和选择性合并接收算法的性能(脢 鹿 脫脙matlab脢渭脧脰cdma 脧渭脥 鲁 渭脛rake 陆 脫脢脮 禄煤 拢 卢 卤 脠 陆 脧 脳 卯)

veirlog编写的PS2键盘通讯程序, 并有PS2接口的相关说明, Quartus II 8.1工程文件(veirlog written communication procedures PS2 keyboard, and a PS2 interface instructions, Quartus II 8.1 project file)

this program get 20 point from user and draw functions.

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the lock data the rising and falling edge; top-level document is PLL.GDF

OPSK调制解调。代码思路很清晰，也很干净(Modulation demodulation OPSK. The code ideas very clear, and very clean)

说明：  FPGA——IP_RAM实验： 创建IPRAM核，单端口，10位地址线（256字节），8位数据线（每字节8byte），读写使能 input [9:0] address; input clock; input [7:0] data; input wren; //置1则写入 output [7:0] q; LNXmode：控制LEDC显示 1：mode1，从k1~k3输入data的低4位，ledb计时，从0~f，计时跳变沿读取k1~k3的值，存入RAM 8个数之后，从RAM输出数据，用leda显示，同样每秒变化一次(The experiment of FPGA-IP_RAM: Create IPRAM core, single port, 10 bit address line (256 bytes), 8 bit data line (8 byte per byte), read and write enablement)

高精度小数除法器设计与实现。 在FPGA开发板上实现小数除法器，输入输出信号N_in [15:0], D_in[15:0]，N_in[15:0]小于D_in，即被除数小于除数，输出商Q_out[15:0]中Q[15]一定为0，Q[14:0]为商的小数部分。输入和计算结果通过VGA显示。(Precision fractional divider design and implementation. In the FPGA development board fractional divider, input and output signals N_in [15: 0], D_in [15: 0], N_in [15: 0] less than D_in, ie the dividend is less than the divisor, quotient output Q_out [15: 0] in Q [15] necessarily 0, Q [14: 0] for the business of the fractional part. Input and calculation results display by VGA.)
