VLSI加法器

用NiosII实现的数字钟，经过本人测试运行正常，开发环境：QuartusII6.0和NiosII IDE6.0-NiosII achieved with digital clock, after I run the normal tests, development environment: QuartusII6.0 and NiosII IDE6.0

实现pwm波的输出，按键可调占空比的，可通过连接pwm输出值led灯以检测占空比的变化(To realize the output of the PWM wave, key adjustable duty ratio, but through the connection PWM output value led lamp with testing duty ratio changes )

这是用verilog硬件描述语言编的5分频代码-This is verilog hardware description language code is compiled by five divider

介绍了FPGA设计的十大准则，对初学者很有用，对于工作多年的同志，也会有整理总结的好处-Describes the FPGA design of the top ten criteria are useful for beginners, for many years comrades, there will be finishing the benefits of the summary

FFT implementation using C program

verilog 编写的比较最大值最小值得的程序，而且能够求出最大最小值在ram中存储的位置，测试通过下载即用(Comparison of the maximum write verilog smallest worthwhile program, and minimum and maximum values ​ ​ can be obtained is stored in ram position, the test that is used by downloading)

说明：  利用FPGA实现对外设按键的控制，例如用户库用按键控制跑马灯的效果(FPGA is used to realize the control of external keys, such as the effect of user database using keys to control the running horse lamp)

使用Altera公司的FPGA进行VHDL开发。使用quartus2 9.0软件在EP1C3T144C8开发板上实现对4x4键盘的输入控制，并显示在一个8段式数码管上。-The use of Altera" s FPGA-VHDL development. Use quartus2 9.0 software EP1C3T144C8 the development board to realize 4x4 keyboard input control, and displayed in an eight-stage digital pipe.

用verilog实现dsp与Fpga接口的同步设计，其功能包括读写操作及四个功能模块，采用两个fifo实现不同时钟域的地址与数据的转换，在quartus ii11.0环境下运行，运行此程序之前需运行将调用fifo。(Dsp using verilog achieve synchronization with Fpga interface design, its features include read and write operations and four functional modules, using two different clock domains to achieve fifo address and data conversion in quartus ii11.0 environment to run, run this program required before running calls fifo.)

并口通讯代码 并口通讯代码（调试通过） --该代码目前能实现单个字节的收发-Parallel communications code (debugging through)-- The code can now achieve a single byte of Transceivers
