数字频率计 FPGA 用verilog语言编写

protel fpga常用封装库1，非常难找的-protel fpga library a popular package is very difficult to find the

Block LU decompostion of a matrix

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)

本代码仿真了WCDMA小区搜索。cell_search_cpich scramble wcdmasource(This code emulation WCDMA cell search. cell_search_cpich scramble wcdmasource)

该程序是在d，t，jk触发器上用vhdl语言编写的

采用Verilog HDL设计,在掌宇智能开发板上得到实现 根据抢答器的原理，整个电路可划分为三部分：采样电路、门控电路和译码电路- Uses Verilog the HDL design, obtains the realization basis on the palm space intelligence development board to snatch the answering principle, the entire electric circuit may divide is three parts: The sampling electric circuit, the gate control the electric circuit and the decoding circuit

交通灯电路，南北方向和东西方向分别按绿灯、黄灯、左拐灯、黄灯、红灯的顺序两灭，数码管显示相应的灯亮的时间的倒计时。已通过编译和仿真。-Traffic light circuit, north-south direction and east-west direction respectively green, yellow light, left light, yellow light, red light destroy the order of two, a digital LED display lights the corresponding period of the countdown. Has passed the compilation and simulation.

电子表，实现计时记分计秒的功能，同时可以对时分秒进行校正，实现调时功能。-Electronic watches, time points of dollars to achieve a second function, at the same time when the minutes and seconds can be calibrated to achieve when the transfer function.

这是Xilinx ISE 14.X以及vivado、vivado_hls的license，亲测可用(Xilinx ISE 14.x vivado, vivado_hls license, pro-test available)

用于实现fpag-cpu的数据通路源代码。用vhdl编写，包括内存，寄存器组，和alu（简陋的alu，仅包含加法器）三大部分通过手动微指令输入信号，可以往内存写入数据，并加载到寄存器组中，通过alu产生结果，结果保存在一个锁存器中，可以把结果写回寄存器组或者内存。本人在quartus下编写仿真通过。附件中未给出相关工程文件。
