4：2优先编码器的VHDL代码

说明：  十进制到十六进制转换的程序。程序要求从键盘取得一个十进制数，然后把该数以十六进制的形式在屏幕上显示出来。(Decimal to hex conversion program. Procedural requirements to obtain a decimal number from the keyboard, and then the hexadecimal number to be displayed on the screen.)

减1计数器 一、设计要求 用Verilog HDL语言设计一个计数器。 要求计数器具有异步置位/复位功能，可以进行自增和自减计数，其计数周期为2^N（N为二进制位数）。 二、设计原理 输入/输出说明： d：异步置数数据输入； q：当前计数器数据输出； clock：时钟脉冲； count_en：计数器计数使能控制（1：计数/0：停止计数）； updown：计数器进行自加/自减运算控制（1：自加/0：自减）； load_d-a counter a reduction, design requirements using Verilog HDL design of a counter. Asynchronous requests with counter-home/reset functions can be carried out by self and self-count reduction, cycle counting of 2 ^ N (N for binary digit). Second, the principle of design input/output Description : d : asynchronous home several data input; Q : The current counter data output; Clock : clock pulse; Count_en : Counting enable control (1 : Counting/0 : Stop counting); Updown : dollars several self-Canada/reduction Operational control (1 : Since the plus/0 : Since decrease); load_d

完整的TPC编译码VHDL程序，直接就可以运行(TPC encoder and decoder)

Rotary Encoder Reading the Rotary Encoder and indicating the selection through a LED placed on the front panel. Events counter for the Rotary Encoder and displaying the events on the front panel Project: events counter for the rotary encoder and displaying the events on the SSD Pmod (Seven-Segments Display Programable module).

一个视频信号输入的verilog源代码，里面含有相关的使用文档。-A video signal input of the Verilog source code, which contains documents related to the use.

说明：  16点verilog FFT，可供参考学习使用(16 points Verilog FFT can be used for reference)

eda技术与vhdl课件,很经典的学习课件-VHDL EDA technology and courseware, it is a classic learning courseware

用vhdl语言编写的基于FPGA的波形发生器。对于做实验需要产生的波形非常有用。-VHDL language using FPGA-based waveform generator. Does the need for experimental waveforms generated very useful.

说明：  使用FPGA实现中值滤波算法，能够使数据直接使用该系统对数据进行中值滤波。(FPGA is used to realize the median filtering algorithm, which can make the data directly use the system for median filtering.)
