VHDL硬件描述语言与数字逻辑电路设计

通过MATLAB产生单脉冲信号的数据，存储下来作为verilog代码实现的DDS的数据源，用于验证DA数据的ddio的调试是否有问题。(The data of monopulse signal generated by MATLAB is stored as the data source of DDS implemented by Verilog code to verify whether the ddio debugging of DA data is problematic.)

本实验为UART回环实例，实验程序分为顶层unrt_top、发送模块uart_tx、接收模块 uart_rx，以及时钟产生模块clk＿div。uart＿rx将收到的包解析出8位的数据，再传送给 uart_tx发出，形成回环。参考时钟频率为100MHz，波特率设定为9600bps。(This experiment is an example of UART loop. The experimental program is divided into top-level unrt_top, sending module uart_tx, receiving module uart_rx, and clock generation module clk_div. Uart_rx parses the received packet into 8 bits of data and sends it to uart_tx to send out, forming a loop. The reference clock frequency is 100 MHz and the baud rate is set to 9600 bps. stay)

:针对现场可编程门阵列(FPGA)芯片的特点,研究FPGA中双向端口I/O的设计,同时给 出仿真初始化双向端口I/O的方法。采用这种双向端口的设计方法,选用Xilinx的Spartan2E芯片 设计一个多通道图像信号处理系统。-: For field programmable gate array (FPGA) chip features of FPGA in the bi-directional port I/O design, the simulation is initialized at the same time two-way port I/O method. Using this design method of two-way ports, optional Spartan2E the Xilinx chip to design a multi-channel image signal processing system.

一般网站上都有i2c master模块的代码,但很少有slave的代码,这里就是slave的代码,非常有用.-general website have i2c master module of code, but very few slave code, This is the slave code, very useful.

VHDL的初学者可以参考此VHDL加法器，相信会给你带来不小的收获-VHDL beginner can refer to the VHDL adder, I believe will bring you not a small harvest
