FPGA设计的I2C总线控制器的MASTER端的程序

介绍了FPGA设计的十大准则，对初学者很有用，对于工作多年的同志，也会有整理总结的好处-Describes the FPGA design of the top ten criteria are useful for beginners, for many years comrades, there will be finishing the benefits of the summary

是51单片机常用头文件定义，直接调用就可以，包括：1602液晶，12864液晶，5110屏，I2C,UART,精确延时函数，PWM调速，DS1302，DS18B20,,,,,,,(51 microcontroller used header file defines direct call can include: 1602 LCD, 12864 LCD, 5110 screen, I2C, UART, precision delay function PWM speed control, DS1302, DS18B20,,,,,)

LDPC的短码，码长为40速率为0.5的LDPC码的设计，用的是QC矩阵，压缩文件为原码部分，工程太大传不上去。(LDPC short code, a code length of 40 rate of 0.5 LDPC code design, using a QC matrix, the compressed file is part of the original code, do not pass up the works too.)

QPSK调制，QPSK仿真误码率,QPSK理论误码率 , QPSK仿真误比特率 , QPSK理论误比特率 (QPSK modulation, the signal-to-noise ratio)

512阶高速FIR成型滤波器，四相位复用，树形加法和多级流水线结构。(512-order high-speed FIR shaping filter, four-phase re-use, tree addition and multi-stage pipeline structure.)

说明：  多通道连续声发射数据采集，每个通道最大5M，采用verilog编程，内部用状态机。(Multichannel continuous acoustic emission data acquisition, each channel up to 5M, using Verilog programming, internal state machine.)

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

verilog vga 图像处理(verilog vga)

由VHDL 语言实现的数控分频 利用的是QUARTUES环境已经得到验证-By the NC VHDL language is the use of sub-frequency QUARTUES environment has been tested
