该程序用来实现电话计时以算取费用，比较简单(telephone cost metering verilog code)

xilinx公司的virtex-5开发板原理图 需要的可以下载看一下 希望对你有帮助(xilinx company virtex-5 development board schematics can download look you want to help)

Encryption has become a part and parcel of our lives and we have accepted the fact that data is going to encrypted and decrypted at various stages. However, there is not a single encryption algorithm followed everywhere. There are a number of algorithms existing, and I feel there is a need to understand how they work. So this text explains a number of popular encryption algorithms and makes you look at them as mathematical formulas.

基于DE2开发板的VGA显示模块，仅供大家参考(DE2 development board based on the VGA display module, for your reference)

说明：  FPGA测试程序，仅供测试硬件是否能够运行，主要功能是点亮运行指示灯(The main function of the test program of FPGA is to light the running indicator.)

基于CPLD硬件描述语言编写的五电平SVPWM脉冲触发程序(Five level SVPWM pulse trigger program based on CPLD hardware description language)

说明：  altera fpga 实现fft，用fft IP核，有matlab仿真代码(Altera FPGA implementation of FFT, FFT IP core, matlab simulation code)

说明：  对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)

FPGA做波形发生器，产生8种波形，包括三角波，正弦波，锯齿波，方波等。(FPGA is used as waveform generator,Generate 8 waveforms, including triangle, sine, sawtooth, square, etc.)
