用于检测信号上升沿，输出与时钟相关的正脉冲(Detect the rising edge of the signal)

利用FPGA，产生三相SPWM波，与后继硬件电路配合，形成三相电源。高效，实用。(Using FPGA, produce three-phase SPWM wave, with subsequent hardware circuit with the formation of three-phase power. Efficient and practical.)

UART RS232 IPCORE for sopc builder -RS232 UART IPCORE for sopc builder

基于对ROM的编写，在quartusII上实现九九乘法器的实现，在试验箱的四个数码管上分别显示乘数，被乘数，积

基于VHDL的数字计时器，手动可控正计时和倒计时(含复位键和使能键)(VHDL-based digital timer and countdown timer being controlled manually (with the reset button and enable key))

vhdl测试程序，用于初雪者熟悉hdl的具体语法应用。比较简单了。(VHDL test procedure for the First Snow hdl who are familiar with the application of specific syntax. A relatively simple.)

可直接用于zedboard上的串口通信，利用zynq7000的pl部分实现一个简单的UART串口通信(Can be used directly on the zedboard serial communication, the use of zynq7000 PL part of the realization of a simple UART serial communication)

设计一4位比较器,画出门级电路图,用verilog语言完成设计。 (Design a four comparators, drawing out level circuit diagram, complete the design using verilog language. )

说明：  本光盘是《数字信号处理FPGA实现》一书的配书光盘，内容包括了书中第二章给出的所有示例以及该书的12个实验完整的工程文件。 本光盘根目录下有3个文件夹，分别为dsp48_application,dsp48e_application和DSP_Example。(This CD-ROM is the CD-ROM of the book "FPGA implementation of digital signal processing". It includes all the examples given in Chapter 2 and the complete engineering documents of 12 experiments in the book. There are three folders in the root directory of this CD-ROM, which are dsp48_ application,dsp48e_ Application and DSP_ Example.)
