摘要:

快速启动技术是嵌入式Linux的关键技术之一,在消费类电子领域有很好的应用价值。本文分析了嵌入式Linux的启动延时分布,比较了多个适合嵌入式Linux的文件系统的特性,给出了一种适用于消费类电子领域并支持快速启动的文件系统结构,并结合XIP技术,较好地解决了嵌入式Linux的快速启动问题。

关键词: XIP 快速启动 嵌入式Linux 嵌入式Linux文件系统

Abstract:

How to reduce the booting time of the embedded Linux is one ot the key technologies of Embedded Linux, and particularly it is very useful and necessar y for embedded Linux to be used in consumer electronic products. This paper analyses the delay areas of Embedded Linux, and compares the characteristics of file systems which are suitable for Embedded Linux. According to the results, we design a file hierarchy which is suitable for consumer electronic L  inux and supports fast Looting. Meanwhile, we combine it with XIP(Execute In Place) to reduce the delay of hoot time further.

Key words: XIP, fast booting;embedded Linux, embedded Linux file system
