基于vhdl开发的频率发生器

wavelet transform of a signal,it is important and useful code to trans form frequency to time domain

PS2的源代码VHDL语言实现，可以和计算机直接连接．做鼠标键盘接口．-PS2 source VHDL, and can be connected directly to the computer. So the mouse, keyboard interface.

此vhdl程序实现了在FPGA上构建UART通信串口。分为两部分，UART的发送端transfer和接收端receiver。需要外部根据需求提供波特率时钟。(This program implements the building vhdl UART serial interface on the FPGA. Divided into two parts, UART transfer sender and receiver receiver. Required to provide the baud clock external demand.)

电梯的vhdl设计，6层楼含开关门，警报，内部请求，外部请求-Vhdl elevator design, six floors with switch doors, alarm, internal requests and external requests

这是我准备电子设计大赛时，用VHDL写的一个自动打铃系统，很好的学习资料。-This is when I am going to Electronic Design Contest, use VHDL to write an automatic bell playing system, a very good learning materials.

用VHDL语言写的VGA核心,是个很好很齐全的核心,有很多功能.-write VHDL VGA core, is a very good subset of the core, has a lot of functions.

说明：  Matlab to hdl code for Least_square testbench

本代码是实现了lwip协议栈,可以移植到其他类型的嵌如式操作系统上-This code is to achieve a lwIP protocol stack can be ported to other types of embedded operating systems such as the type
