Verilog DDS发生器的实现

This is hardware implemented Gaussian random number generator based on the article attached in the folder "Document" The system is based on the Ziggurat Gaussin random algorithm and implemented when I was under-graduate. Although it is not my original system, it is so helpful cause I can acquire a lot of useful skills of verilog programming such as pipeline. It is well simulated on the synthesis tool (ISE14.7) and the printed data can be verified using Matlab which is in the "Document" folder. The testbench fils is tb_Zigg.v, and the top module file is top_Zigg.v Goodlucks~

接口模块，通过对高位地址的编码可实现在一个FPGA中配置四个独立的功能模块，每个功能模块具有一个带FIFO的输出口和13个独立的可由DSP读写的寄存器，寄存器功能可自定义。模块还包含两个全局寄存器，可实现全局复位，中断等功能。该模块以应用于实际的项目中，目前运行良好(FPGA to emif)

very nice program that i ensure anyone can use easily and will be efficient for hard project of elevator

1、FSMC全称是静态存储控制器，用来高速操作外部SRAM，NOR，NAND等，广泛用来驱动LCD MCU的FSMC配置在fsmc_nor.c，你也可以查阅相关资料。 2、此例程通过读写外部M29W128，熟悉FSMC的配置以及操作。(1, FSMC stands for static memory controller for high-speed operation of external SRAM, NOR, NAND, widely used to drive the LCD MCU FSMC configuration in fsmc_nor.c, you can also access to relevant information. This routine by reading and writing external M29W128 familiar with the configuration and the operation of the FSMC.)

数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)
