VHDL Programing

用vhdl设计实现的多功能电子钟，可有日历，闹钟，修改等多种功能-With VHDL Design and Implementation of the multi-functional electronic bell, can have a calendar, alarm clock, to amend a variety of functions such as

说明：  Viterbi译码,IS-95中的1/2码率的卷积码(Viterbi decoding, IS-95 of 1/2 the rate Convolutional Codes)

XAPP928,可以参考学习.里面包含了色温调整、GAMMA调整以及空间抖动增强灰度算法，这３个基本是现在平板显示设备常用的图像预处理算法。

it has 6 packages of 8051 sources,including source code(VHDL and Verilog),dc scripts, pdfs, netlists etc. and a MIPS IP package

Efficient CIC filter Implementation using VHDL

程序设置了fpga 的 5x5点阵驱动程序，代码相对比较简洁，这个程序可以作为fpga输出控制，驱动稳压芯片工作，进而点灯

控制三相步进电机及光电编码器的采集,当电机停止时,保证三相里面只有一相相通,防止停止时电流过大.(Control three-phase stepper motor and optical encoder collection, when the motor stops to ensure that only one phase of three-phase inside the heart, and to prevent too much current is stopped.)

pcf8563，在quartusII下VERILOG编写的数字时钟程序，8位数码管显示(pcf8563, written in quartusII VERILOG digital clock program, eight digital display)

说明：  采用vhdl语言编写的卷积编码（2.1.7），通过调试可直接下载使用(Convolution using vhdl language code (2.1.7) can be directly downloaded through the use of debugging)

fpga实现ddr数据收发测试，完整的工程，下载解压后，即可正确运行，已多次验证无误(FPGA DDR data receive and receive test, complete engineering, download and unzip, can run correctly, has been verified many times)
