verilog UART 波特率

自己写的FPGA实现电子琴的VHDL程序，曲目是两只老虎，用到一些模块，和片内存储间，呵呵(FPGA realization of his keyboard to write the VHDL program, tracks are two tigers, a number of modules used, and on-chip storage room, huh, huh)

VHDL Code For Full Adder By Data Flow Modelling

基于verilog-a的自建模型，可以作为任何代建模型的参考，理解hspice模型的构成，内在根本机理。

用verilog语言编写的4位算术逻辑单元ALU,功能参考74181，包含.v文件以及测试用.vwf文件(Verilog languages with four arithmetic logic unit ALU, functional reference to 74,181, including. V documents and testing. Vwf document)

异步FIFO，包括测试代码，可直接使用，测试时使能读写命令winc和rinc信号恒为1，测试其读写能力。

利用FPGA控制VGA显示器显示字符汉字的程序，里面有注释。(VGA display with FPGA control procedures Kanji characters, there are comments.)

利用VHDL 硬件描述语言设计一个0~9999 的加法计数器。根据一定频率的触发 时钟，计数器进行加计数，并利用数码管进行显示，当计数到9999 时，从0 开始重新计数(Use of VHDL hardware description language design a 0 ~ 9999 addition counter. According to a certain frequency of the trigger The clock, counter add count, and use digital pipes to show that when the count to 9999, starting from 0 to count )

自己搜集的一些FPGA指南教程，包括一些高工们的经验之谈、设计原则，目前正在学习，有一定帮助，分享给大家(Gather their own of some FPGA guide tutorial, including some senior engineers are the voice of experience, design principles, are learning to have some help, to share to everyone)

FPGA实现反正切功能，工程原件，包括测试文件，能够很好实现该功能(FPGA implements arctangent function, original engineering)

ep9351芯片的一个读取寄存器的测试程序，因为他的读取方式跟别的i2c设备不同，所以重新封装了一些i2c读写的接口。(one read ep9351 chip registers testing procedures, because he read i2c device with another different way, so repackaging some i2c interface to read and write.)
