Description: 利用framebuffer画小企鹅
Linux的framebuffer接口提供给用户访问显示设备的通用接口，通过mmap映射显示缓冲给用户，fb中我们设置什么值，将直接在屏幕上显示出来。本实验我们要利用framebuffer在屏幕上显示一个小企鹅，可以接读取bmp图片,设置framebuffer的值，或者利用include/linux/linux_logo.h文件（该文件已经定义好小企鹅的颜色和位置信息），设置framebuffer的值。本实验采用的是第二种方法。只要读取linux_logo.h中数组的值，进行相应的移位操作，将值赋给fb即可在屏幕上显示出小企鹅 。-Framebuffer draw using the framebuffer Little Penguin Linux interface to the user access to the display device of the common interface, through mmap mapped display buffer to the user, fb set up what we value, will be directly displayed on the screen. This experiment we want to use framebuffer on the screen, a small penguin, you can then read bmp images, set up framebuffer value, or the use of include/linux/linux_logo.h file (the file has the definition of a good little penguins color and location information) , set the value of framebuffer. Used in this experiment is the second method. Linux_logo.h read in as long as the value of the array, the corresponding shift operation, the value assigned to fb can be displayed on the screen small penguins. Platform: |

Description: SDL是Simple DirectMedia Layer（简易直控媒体层）的缩写。它是一个跨平台的多媒
体库，以用于直接控制底层的多媒体硬件的接口。这些多媒体功能包括了音频、键盘和鼠标
（事件）、游戏摇杆等。当然，最为重要的是提供了 2D图形帧缓冲（framebuffer）的接口，
以及为 OpenGL 与各种操作系统之间提供了统一的标准接口以实现 3D图形。从这些属性我
们可以看出，SDL 基本上可以认为是为以电脑游戏为核心开发的多媒体库。-SDL is the Simple DirectMedia Layer (simple direct control of the media layer) of the acronym. It is a cross-platform multimedia
Physical library to be used for direct control of the underlying multimedia hardware interface. These multimedia features include audio, keyboard and mouse
(Event), joysticks and so on. Of course, the most important is to provide a 2D graphics frame buffer (framebuffer) interface,
As well as a variety of operating systems with OpenGL to provide a unified standard interface in order to achieve 3D graphics. I am from these properties
Can be seen, SDL is basically a computer game that is the core of the development of multimedia library.

Description: framebuffer文件实例
framebuffer是出现在内核中的驱动程序的接口。
他把显示设备抽象的映射到帧缓冲区——可以认为是显存！
可以把它看成是显示内存的一个映像，将其映射到进程地址空间以后，就可以直接进行读写操作，并且写操作可以直接反应在屏幕上。
