一个用VerilogHDL语言编写的模6的二进制计数器

TEXIO study testbench passed VHDL FPGA CPLD simulation Altera quartus

我自己当初用来求解arctan 暂时没有搞成ip形式 搞好了还要传git 这个代码还没有搞好，因为急需要下载东西 如果感兴趣可以联系我 邮件(this is a not full wrappered code very crude use chebyshev to caculate arctan function i m urgent to download a model from pudn so i do this.)

Altera DE2 上使用 vhdl 语言设计 RS232 控制器。这是一个串口模块可用于嵌入系统。

电子打铃器 在max plus 2 下编译通过-electronic bell playing for the max plus 2 under through compiler

使用verliog实现ps2键盘接口的驱动，通过altera cyclone 第四代验证通过(Use verliog implement ps2 keyboard interface driven by a fourth-generation verified by altera cyclone)

verilog语言设计的VGA驱动。在Quarus11.0下编译成功，并在Altera cyclone4开发板上测试OK(verilog language design VGA driver. In Quartus11.0 successfully compiled and Altera cyclone4 development board test OK)

连乘,乘法可以用简单的for循环，我这里用的是移位寄存器来做，而且是用来两个移位寄存器(this is a tool that function is multiplay,it use a special way to do multiplay .it will teach you the how to use labview )

共两个文件，一个是对网络芯片W5500进行控制的master spi接口，另一个是w5500命令控制逻辑，命令格式按照w5500芯片的要求，分为地址段，控制段和数据段进行统一控制。此外提供w5500芯片初始化及读写控制流程图。(A total of two documents, one is the master SPI interface for network control chip W5500, the other is a w5500 command control logic, command format in accordance with the requirement of w5500 chip, divided into address segment, unified control and data segments. In addition to provide w5500 chip initialization and read and write control flow chart.)
