Linux下的帧缓冲设备驱动研究与应用

帧缓冲(framebuffer)是Linux内核为显示设备提供的一个接口。对Linux下帧缓冲技术的实现原理,帧缓冲驱动程序的体系结构进行了讨论。以Linux2.6.28和飞思卡尔半导体的MX51处理器为系统设计的软、硬件平台,以高清视频输出系统中的DVI驱动设计为例,分析了嵌入式应用系统中,帧缓冲设备驱动程序的实现框架和设计方法。

Framebuffer Device Driver Study and Application on Linux

Framebuffer is a standard interface of Linux kernel for display devices.This paper disscusses Linux framebuffer realiza- tion principle and framebuffer driver＇s architecture.Next based on Linux2.6.28 kernel and Freescale MX51 processor system platform.This paper uses DVl driver of HD video output sysetem as an example to analyze framebuffer driver＇s realization architecture and design method in embedded application system.
