基于FPGA实现的一种新型数字锁相环-FPGA-based realization of a new type of digital phase-locked loop

ALTERA PCIE FPGA开发板（EP4C平台）DDR2内存测试代码(ALTERA PCIE FPGA development board (EP4C platform) DDR2 memory test code)

使用VHDL编写语言，巧妙的利用计数器和循环输出一个坐标系，由于VHDL出现负数比较麻烦，全部由正数代替，输出一个原点在中心，半径128的256×256的坐标。方便坐标变换以及用此坐标做算法。(Use of VHDL language, clever use of counter and loop outputs a coordinate system, because VHDL negative too much trouble, all replaced by a positive number, the output an origin at the center, radius 128 256 256 coordinates. Convenient coordinate transformation and coordinate to do with this algorithm.)

本文首先对多功能车辆总线的基本原理进行了简要的概述，接着对其实时协议进行了分析，然后对 MVB2 类设备控制器的功能及其功能模块的划分设计进行了详细的分析；最后对各功能模块进行了编程实现，并给出了仿真验证波形。(Firstly, the basic principle of the multifunction vehicle bus are briefly outlined, then analyze the real time protocol, then carried out a detailed analysis of the classification of the design function and the function module of the MVB2 device controller; finally, the function of each module of the program, and gives the simulation waveforms.)

这是使用VHDL编写的交通灯程序,供大家交流学习-This is the use of VHDL prepared by the traffic lights procedures for the exchange of learning

LS165移位寄存器的verilog语言编写(The writing of the Verilog language of LS165 shift register)

VHDL汇编语言原理及源代码。spartan 3e开发板试用。(VHDL language.)

本代码介绍了使用VHDL开发FPGA的一般流程，最终采用了一种基于FPGA的数字频率的实现方法。该设计采用硬件描述语言VHDL，在软件开发平台ISE上完成，可以在较高速时钟频率（100MHz）下正常工作。该设计的频率计能准确的测量频率在1Hz到100MHz之间的信号。使用ModelSim仿真软件对VHDL程序做了仿真，并完成了综合布局布线，最终下载到芯片Spartan-II上取得良好测试效果。-the code on the FPGA using VHDL development of the general process, finally adopted a FPGA-based digital frequency method. The design using VHDL hardware description language, the software development platform ISE completed, the higher speed clock frequency (100MHz) under normal work. The design of the frequency meter can be accurately measured in a frequency of 100MHz between Hz signal. Use ModelSim VHDL simulation software to do the simulation process, and completed a comprehensive layout cabling, downloaded to the final chip Spartan-II made good on the test results.
