FIR滤波器的VHDL语言实现

用于fpga学习，共同分享学习经验和交流学习心得-For fpga to learn, to share learning experiences and the exchange of learning

PS2键盘LCD显示控制器的vhdl代码，很难得(PS2LCDController vhdl code)

说明：  可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

DSP与FPGA时序接口模块，已经经过测试，保证读写稳定(The Interface of DSP to FPGA)

This is a divider, which is depicted as well. It is a programming language Vhdl.

VHDL开发的计数器。源程序不复杂，应该都能看懂。最重要的注意：是时序问题-VHDL development of the counter. Source code is not complicated, should be able to understand. The most important Note : Timing is the issue

倍频器-WE

本文是自已写的电子密码锁的详细开发过程，用的是Modelsim进行仿真实现，打开文档lzp-This article is written in their own electronic locks detailed development process, using a ModelSim simulation achieved, open the document lzp

用Verilog语言实现QPSK调制，QPSK是一种数字调制方式。它分为绝对相移和相对相移两种。 (Verilog language using QPSK modulation, QPSK is a digital modulation. It is divided into absolute and relative phase shift of the phase shift of two.)
