Embedded Operating System Migration Visualization Configuration

Nowadays, embedded system developed rapidly. It was used in every field of social,among which are the field from automatic navigation of space shuttle to the field ofmobile phone and intelligent home electrical appliance. More and more companies andindividuals were abstracted by it. In the progress of an Embedded System developed,porting Embedded Operating System to the target is one of the most important works ofall. The traditional porting method requests the developers have comprehensiveknowledge on architecture and mechanism of Embedded Operating System, and modifythe code of Embedded Operating System relative to the system hardware according to thetarget. This period will be long and tough. Making the porting be easy and rapidly will bequite significant and worthy to the developing of Embedded System.The measure that using the visible configuration technology (inputting hardwareconfiguration parameters by the graphic interface), and taking advantage of the sourcecode auto-generated procedure to generate the source codes as many as possible (whichare related with the specified hardware), could greatly simplify and accelerate the portingof Embedded Operating System.This article first gives a description about the software and hardware of embeddedsystem,and then gives a description about the technology of visible configuration in theenvironment of embedded system generally, third analyses three kind of architecture andbootloader of embedded processor(ARM, MIPS, PowerPC) and corresponding visibleconfiguration, forth analyses three kind of porting method of Embedded OperatingSystem (μC/OS-Ⅱ,Linux,VxWorks) and corresponding visible configuration, fifthprovides the approach of implementing the visible configuration. It also gives a visibleconfiguration tool based on ARM bootloader. Finally, the article gives a view of thefuture of the visible configuration in the porting of Embedded Operating System.
