数字电子钟设计完整设计，包括原理介绍，程序设计，波形仿真...

Very good info. for RS-232 echo VHDL code .

该程序是一个可完成订制化的SPI双向总线接口，时钟相位、极性，以及分频比全部可通过寄存器进行配置，已经在ISE下通过综合，占用资源少，强烈推荐 (The program is a complete custom of SPI bidirectional bus interface, clock phase, polarity, and the divider ratio can all be configured through the register, has been in the ISE through an integrated, small footprint, it is strongly recommended)

QPSK调制的载波频偏估计，是一个可以调用的函数。接收端进行了一系列的处理。经典的Fitz法(QPSK-carrier frequence offset estimation_ Fitz)

Xilinx FPGA中FFT IP核的使用笔记，内部有FFT硬核的端口说明和具体设置以及源代码，对于数字信号处理研究人员，能图像处理、雷达成像、实时通信开发人员较多的开发时间！(Xilinx FPGA in the FFT IP core using a laptop internal hard core of the FFT port description and specific settings as well as the source code for digital signal processing, image processing, radar imaging, real-time communications developers more development time!)

这是一个语音程序,通过VHDL编译了.大家可以直接调用.其中还包括了键盘程序有需要可以下来-This a voice procedures, through a VHDL compiler. you can directly call. It also includes a keyboard procedures need to look at it down

NAND型闪存接口程序 里面包含了datasheet以及测试程序 (NAND flash memory interface program)
