Power design of hand-held devices based on ARM embedded platform

Along with information science and technology progress, electronic application product innovates unceasing and the people more and more are also high regarding the electronic products request. In this paper, a hand-held device with the conformability, functionality, portability, convenience, and customization based on ARM embedded platform will be implemented. The hardware specification definition, development tools choice, and circuit design and debug will be introduced first. And then the power design for the units including memory, usb, uart, and LCD&TOUCH screen will be investigated. The debug algorithm will also be programmed such that the system can be designed systematically. Finally, the discussions of the system design problems will be made and the test results will show that the developed device can achieve the specifications actually.
