地铁售票系统，基于VHDL，可实现站点设置，站点选择，选择购票数量，找零等一系列功能。...

Fixed-point base-2 logarithm (DW_log2) // Computes the base-2 logarithm of a fixed point value in the // range [1,2).

说明：  在MATLAB下自编实现快速傅里叶分析，(Fast fft own procedures, faster than the system call fft slowe)

vhdl code for internet interface

in this code very useful for designing real number concept

曼彻斯特编解码，是Verilog语言代码，不多介绍了，用途非常广泛了-Manchester encoding and decoding is the Verilog language code, introduced a few, a very extensive use

ADS7809是Burr-Brown公司推出的高精度AD采集芯片。它采用5V单电源供电,内含16位 逐次逼近寄存器,采样精度高,功耗小。 用Verilog实现其配置(ADS7809 is a Burr-Brown Introduces High Precision AD capture chip. It uses a single 5V supply, with 16-bit successive approximation register, sampling and high precision, low power consumption. To achieve its configuration with the Verilog)

完成一个1位全减器的设计。以全减器为元件程序完成8位减法器设计。(Completed a one minus the whole design. Full reduction is to complete eight subtraction element program design.)

基于verilog语言的差分曼彻斯特编码，内包含数据的采集，CRC校验（8位），和编码，输出。附有完整的工程文件。可直接调用modelsim仿真。(Based on differential Manchester encoding verilog language, and contains data collection, CRC check (8), and coding. With complete project file. Modelsim simulation can be called directly.)

通信中常用的PN序列产生器的源代码全部打包(Communications commonly used in PN sequence generator, the source code of all packaged)
