代码说明:

  熟悉IIC协议总线协议,采用IIC总线对图像采集传感器寄存器进行配置,并转换为RGB565格式。 利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。 利用 SDRAM 接口模块的设计,实现了刷新、读写等操作;为提高SDRAM 的读写带宽,均采用突发连续读写数据方式;并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。 利用双线性插值方法实现对图像640×480到1024×768的放大操作。 完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format. Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface. With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA. The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768. Complete the VGA display interface design.)

    说明:  我们在整个游戏中,看到的所有内容,我们都理解为游戏对象。 那么每一个游戏对象,都是由一个单独的类创建而来。 为了便于我们程序的可扩展性,减少冗余代码,我们写一个父类,让这些游戏对象的子类 来继承我的父类,我在父类中,将子类中所共有的成员全部都封装起来。 应该记录游戏对象的横纵坐标 需要记录游戏对象的高度和宽度(All the content we see in the whole game is understood as the object of the game. Then every game object is created by a separate class. In order to facilitate the scalability of our program and reduce redundant code, we write a parent class to let the children of these game objects. To inherit my parent class, I encapsulate all the members that are common in the subclass. The abscissa and ordinate coordinates of the game object should be recorded You need to record the height and width of the game object)

  • 基于RBF神经网络(径向基)的非线性函数的拟合
    说明:  该程序是对非线性函数进行拟合,并不是多输入单输出。采用RBF神经网络/径向基网络,对非线性函数进行回归拟合。(The program is to fit the non-linear function, not multi-input single-output. RBF neural network/radial basis function network is used to fit the non-linear function.)

    Q1 Create a program that will initialise Port2 bits 0 - 7 to outputs. Then in an endless loop perform the sequence of bit manipulations shown below. Your program should use bit masking operations. Here is an outline of the program in pseudo-code and with the first two bit manipulations done for you. //initialise port 2 for output //set all outputs to 0 while(1) { FIO2PIN |= 0x04 // set bit 2 on (0x04 = 00000100) FIO2PIN &= ~0x04 // set bit 2 off //set port2 bit 1 on //set port2 bit 1 off //set port2 bit 4 on //set port2 bit 6 and bit 7 on //set port2 bit 4 off //set port2 bit 6 and bit 7 off
