cyclone和cyclone2用在5v系统里使用方法,使得FPGA芯片在5V系统中兼容-cyclone and cyclone2 system used in the use 5v, making FPGA chip compatible with the 5V system

一个精确时钟的v-log程序，只用一个全局时钟，增加了精确度(An accurate clock in the v-log program, only one global clock, increased accuracy)

FPGA时序分析说明。对于高速时钟设计中的时序分析与约束有帮助(FPGA,TIME)

基本的usb驱动程序的编程方法,值得一看.-Basic programing method for USB driver, worth reading

数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

本文提出了降低动态功耗有限 Imppulse 跃 (FIR) 数字滤波器的方法这些方法包括低功耗串行乘法器和串行加法器、 移位/添加的乘数，折叠组合展位乘数线性相位结构的改造和应用对 fir 滤波器，以减少功率引致此干扰的消耗也是减少。最小的功率，实现是在基于 8taps 和 8bits 的投入在 100 MHZ 转变/添加乘数 fir 滤波器的功率为 110mw 和 8bits 系数。拟议的 FIR 滤波器，合成了采用 Xilinx ISE 斯巴达 3E FPGA 和权力分析了使用 Xilinx XPower 分析器。

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

这是一个二进制的最简单分频器，是一个简短的fpga代码，用verilog书写(This is the most simple of a binary frequency divider, the fpga is a short code, written in verilog)
