匹配滤波器的verilog实现

说明：  配置ADS4449,SPI接口；中文说明不能小于20字(Configure ads4449,Chinese description cannot be less than 20 words)

级联积分梳状(CIC)滤波器是一种被广泛应用于软件无线电中，可以实现抽取或者插值的高效滤波器。它主要用于降低或提高采样率。CIC滤波器的主要特点是，仅利用加法器、减法器和寄存器，占用资源少，实现简单且速度高。

说明：  本工程使用A7系列FPGA产生DDS，用DAC0832进行正弦电压输出(In this project, A7 series FPGA is used to generate DDS, and DAC0832 is used for sinusoidal voltage output)

本白皮书探讨了在PCI Express的因素 技术可能会影响性能。它还 提供指导如何估算 的系统性能。(This white paper explores the factors in PCI Express technology may affect performance. It also provides guidance on how to estimate the system performance.)

用ALTERA的FPGA实现UDP通信源代码(FPGA UDP)

说明：  设计一个串行数据检测器，当连续输入三个或更多1时输出1，否则输出0(Design a detector for serial data It outputs 1 when three or more 1 input continuously and outputs 0 otherwise)

生成bt656数据格式，针对视频adv7127芯片(Generate bt656 data format,)

FPGA的经典例程，可以进行移植和借鉴使用(FPGA' s classic routines, can be transplanted and learn to use)

Verilog投币式手机充电仪 清华大学数字电子技术基础课程EDA大作业。刚上电数码管全灭，按开始键后，数码管显示全为0。输入一定数额，数码管显示该数额的两倍对应的时间，按确认后开始倒计时。输入数额最多为20。若10秒没有按键，数码管全灭。(Verilog coin operated cell phone charger EDA major homework of digital electronic technology foundation course, Tsinghua University. Just put on the digital tube completely extinguished, press the start button, the digital tube display is 0. Enter a certain amount, the digital tube shows the amount of double the corresponding time, according to the confirmation began countdown. The maximum amount of input is 20. If there is no button in 10 seconds, the digital tube will die out.)

按照手册驱动线阵CCDTCD1209和AD9945，驱动频率10M，板卡时钟30MHz，经PLL分频后输入驱动，该程序在altera cyclone IVE上验证通过
