FPGA、Verilog浮点计算加减乘除

很好的NAND Flash 硬件驱动语言，支持VHDL和verilog 语言方便移植，如果有想用FPGA直接驱动NAND flash而又不知如何下手的朋友肯定喜欢。(NAND Flash Controller Reference This reference design is used to interface a NAND Flash device and provides a simple host end interface. The host end interface of this design is user-configurable. It provides buffer select signal, buffer write enable signal, address bus, data bus, error status signal, control and handshake signals for the user......)

我重视基本的向上和向下计数器。这不是基本up_down counter.this编码方法不同有关。

基于FPGA的神经网络硬件实现中的关键问题研究，适合用fpga研究神经网络的工程人员参考(FPGA-based hardware implementation of neural networks in the study of key issues for research with neural networks fpga reference works)

基于数码管独立显示和三色灯的交通指示系统设计(Design of Traffic Indicator System Based on Digital Tube Independent Display and Tri-color Lamp)

在Quartus环境下编写，使用Cyclong系列芯片，配置七通道高精度AD5791，该例子为AD5791的FPGA配置使能代码,包括模拟数据输入模块，复位模块，命令接收是能配置模块。(AD5781，Digital signal convert to Analog signal)

LCD Interface_Xilinx.CPLD源码参考设计(LCD Interface Xilinx CPLD)

自编的64B/66B编码程序，下次上传解码程序。(the 64B/66B coding process is written by myself, i will upload the decoding process next time.)

/功 能：1.实现与CPLD的通信,从而控制PWM的占空比. 2.实现LCD显示相关信息. // 3.实现对键盘按键的判断和确定相应的操作. 4.实现对电压电流的检测. // 5.实现过载保护功能,电流过大时,切断PWM输出,当排除过流故障后,自动恢复供电 // 6.实现用PID算法跟踪电压,实现稳压输出(/ Function: 1. Achieve communication with the CPLD to control the PWM duty cycle. 2 LCD Display relevant information.// 3. Realize the keyboard keys judgment and determine the appropriate action. 4. Achieve the voltage and current Detection// 5. achieve overload protection, current is too large, cut off the PWM output, when excluding overcurrent fault, automatically restore power// 6. achieve tracking voltage with PID algorithm to achieve the regulated output)

本资料是基于FPGA的AD_DA数据采集系统。所用AD是ADC081S，DA是DAC5311。通过查阅相关的AD_DA时序图，得出驱动程序。这对要写时序的初学者有很大的帮助。

Very suitable for the study using computer vision, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. The performance of the program has reached a high level.
