DDR (double rate) SDRAM controller reference design Verilog code, can be directl...

说明：  文档中的verilog代码实现了FPGA与SSI总线的数据协议链接(Verilog code in the document of the FPGA data bus protocol and SSI links)

图像采集、存储控制verilog源代码，fpga控制SAA1117,采集数据存储到sram，仿真编译测试都能通过(Image acquisition, storage, control verilog source code, fpga control SAA1117, collecting data to sram, simulation tests can be compiled by)

正弦波电流驱动的无刷直流电机性能分析，通过分析方波电流驱动与正弦波电流比较，得出正弦波电流驱动电机性能较好(Sine wave current drive brushless DC motor performance analysis, by analyzing the square-wave current drive with sine wave current comparison, the sine-wave current drive motor performance is better)

可以产生ASK FSK PSK 等调制信号。非常好用已经实现了所有功能。在硬件测试通过了(Can generate ASK FSK PSK modulated signals and so on. Is very easy to use all the features has been achieved. On the hardware test of the)

卷积是在数字信号处理的常见操作。在此项目中，我创建了自定义电路利用大量的并行机制以提高性能与微处理器相比在 Nallatech 主板上实施。卷积将作为输入信号和 kernell 输出是另一个信号，输出信号的每个元素在哪里乘以内核的与输入信号的相应元素的所有元素组成的产品的总和。16 位无符号整数操作使用、 FPGA 将在 SRAM 中存储的输入的信号并将读取在内核中通过内存映射。

本例源代码文件由用户按照书中的操作步骤自己生成，“Example-2-1Project_Navigator_Demo源代码”目录下为源代码的参考文件。“Example-2-1Project_Navigator_Democounter”目录下为完整的工程，包括源代码文件、综合与实现的结果文件、ISE工程文件等，可以使用ISE工程管理器打开工程，供读者参考(In this case the source code files by the user in accordance with the steps the book itself is generated, "Example-2-1 Project_Navigator_Demo source" directory as the source code reference document. "Example-2-1 Project_Navigator_Demo counter" directory for a complete project, including source code files, integrated with the realization of the outcome document, ISE project file, etc. You can use ISE Project Manager, open the project for the reader is referred to)

ADDER USING VERILOG ADDER WITH VERILOG VERILOG ADDER

通过监测工作状态实现带有IIC通讯功能的数据发送接收(to implement the sending and receiving data function of iic communication )

16QAM,64QAM,256QAM调制下的球形译码(16QAM, 64QAM, 256QAM modulation sphere decoding)

说明：  一篇关于LDPC解码算法的FPGA用VHDL实现的PDF文件，老外写的，还可以，可以参考，欢迎大家下载！(A PDF about the FPGA implementation of LDPC algorithm, written by foreigners, but also, you can refer to, welcome to download!)
