The design of the embedded system is advancing towards combination of software and hardware,and the embedded operation system is applied more and more extended.The embedded computer based on ARM and Linux attracts designers' attention by characteristics,such asflexibility,diminishable of software and hardware,highly performance,low cost,and Theresearch in the field is abroad, but the use is little in China.So in this thesis,we work at the application,bring forward some design,and do lots of research in this field.
In the process of design PC/104 embedded computer based on ARM,we go deep into the key technique of embedded system.Because of the disadvantage of traditional x86 embedded computer and the speedy develop of ARM processor,we put forward the idea replacing x86 by ARM in industrial application,and implement the design in production.
First,we discuss the feature of the application of embedded system，emphasizing on development trend of hardware and software respectively Secondly,we lay emphasis on the architecture of ARM link with Linux.Using it to design and implement embedded computer integrated with PC/104 and comparing the performance of ARM and x86 in all aspects. Finally,based on the architecture,we design and implement two kinds of embedded computer in different application.
Keywords: The embedded system ，ARM， PC/ 104 bus
