NAND flash实现ECC

使用信号功率计算，检测信号是否到达。从而控制后续模块，以减小系统功耗。(Signal power calculation, the detection signal to reach. To control follow-up modules to reduce system power consumption.)

这是一个在FPGA上实现CRC算法的程序，包含了CRC-8,CRC-12,CRC-16,CRC-CCIT,CRC-32一共五种校验形式。-err

24,60,100进制的计数器，还有数字时钟，欢迎下载哦~-24,60,100 229 of the counter, digital clock also welcome to download oh ~

iic的代码，是工程文件来的，是XILINX的，来自开源的-IIC

here is a VHDL example

实现对LCD1602的Verilog HDL编程(the program for LCD1602 based on Verilog HDL)

说明：  在zedboard上运行的神经网络架构，方便移植。(Run lenet-5 on zedboard)

数控分频器的输出信号频率为输入数据的函数。用传统的方法设计,其设计过程和电路都比较复杂,且设计成 果的可修改性和可移植性都较差。基于VHDL 的数控分频器设计,整个过程简单、快捷,极易修改,可移植性强。他可利用 并行预置数的加法计数器和减法计数器实现。广泛应用于电子仪器、乐器等数字电子系统中。-NC divider output signal frequency is a function of input data. Using traditional methods of design, process and circuit design are complex and can modify the design of the results are poor and portability. NC VHDL divider based on the design, the whole process simple, fast, easy to modify, strong portability. He can use preset number of parallel addition and subtraction counter counter to achieve. Widely used in electronic equipment, musical instruments and other digital electronic systems.

本源码为Nios II的开发示例,主要演示Nios II的I2C总线设计。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。-The source code for the Nios II development of an example, the main demonstration Nios II I2C-bus design. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.

SPI串口的内核实现（vhdl）,可以用qII等软件直接加到FPGA或者CPLD里面.-the SPI Serial Kernel (vhdl) can be used directly qII software foisted CPLD or FPGA inside.
