Verilog投币式手机充电仪 清华大学数字电子技术基础课程EDA大作业。刚上电数码管全灭，按开始键后，数码管显示全为0。输入一定数额，数码管显示该数额的两倍对应的时间，按确认后开始倒计时。输入数额最多为20。若10秒没有按键，数码管全灭。(Verilog coin operated cell phone charger EDA major homework of digital electronic technology foundation course, Tsinghua University. Just put on the digital tube completely extinguished, press the start button, the digital tube display is 0. Enter a certain amount, the digital tube shows the amount of double the corresponding time, according to the confirmation began countdown. The maximum amount of input is 20. If there is no button in 10 seconds, the digital tube will die out.)

脉动乘法器：一个GF(2m)域上的Digit-Serial 脉动结构（Systolic）的乘法器(Pulse Multiplier: a GF (2m) domain on the Digit-Serial pulsation structure (Systolic) the multiplier)

Implementation of Image Processing Algorithms in FPGA Hardware.

单周期16位CPU的设计,我们的计算机组成原理课设，可以实现R型、I型和J型指令，内有报告和指导书(Single-cycle 16-bit CPU design, our Principles of Computer Organization class set, you can achieve R-type, type I, and J-type instructions, reports and instructions)

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛，本例用VHDL描述了一个锁相环作为参考，源码已经调试过。编译器synplicty.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), the digital technology in the field of communications is widely used, the cases described in VHDL as a PLL reference source has been tuned. Compiler synplicty.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 data locked up and the descending; Top-level document is PLL.GDF
