FPGA产生纳秒脉冲

用verilog hdl语言编写的fpga与片外sram 的读写控制(With the verilog hdl language fpga sram chip with read and write control)

说明：  VHDL资料 很不错的！！！！！！！！！！！(VHDL )

可在FPGA上运行的8051 IP coore，是学习FPGA及SPOC的好资料。 (8051 IP coore, can be run on the FPGA is good information to learn FPGA and SPOC.)

高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)

DE2_115_TV开发板例程，含SDRAM及异步FIFO应用: 通过协调器控制2入2出共4个FIFO操作SDRAM

68013与FPGA的通信，包含了固件程序与verilog程序(68013 and FPGA communication, including firmware and verilog program)

用Verilog代码实现的乒乓操作，用Verilog代码实现的乒乓操作(Verilog pingpong)

通过LED闪烁控制器的代码，使用Vivado工具配置定义一个IP核，在用户工程中可随意添加这个IP核作为设计的一部分，如同Vivado自带的IP核一样方便调用和集成。(Through the code of the LED scintillation controller, the Vivado tool is configured to define a IP core, and the IP kernel can be added as part of the design at random in user engineering. It is as convenient to call and integrate as the IP kernel with Vivado.)

此简化程序模拟并行进，串行出。在 Altera 开发板上成功实施。 在并行进，串行出的情况下，数据以串行方式接受，并且输出后一定数量的时钟周期。

基于verilog语言的差分曼彻斯特编码，内包含数据的采集，CRC校验（8位），和编码，输出。附有完整的工程文件。可直接调用modelsim仿真。(Based on differential Manchester encoding verilog language, and contains data collection, CRC check (8), and coding. With complete project file. Modelsim simulation can be called directly.)
