Research And Implementation Of Mobile Internet Terminal Design Based On The Open Platform

This paper describes the development of the mobile Internet device market and the structure of the industry chain, Analyze the technical environment of the mobile Internet. The mobile Internet is a product of the combination of the Internet, mobile terminal devices and mobile communication technology, we have now entered the early stages development of the mobile Internet, and this is the5th development cycle over the past50years. The growth of the industry will be accelerated.The authors studied the technical architecture of the mobile Internet, and describe its status in the environment of mobile cloud computing, Internet of Things and Smart Home system; discusses the hardware platform architecture of the terminal design, most in application processor. Make a comparative analysis of the architecture based on ARM and X86platforms; analyze the differences and the advantages and disadvantages Android, iOS and other mainstream software operating system.Based on the above analysis, the author uses the design and implementation of mobile Internet terminal based on the open platform as a graduate research project. It uses Nvidia Tegra2dual-core processor hardware platform and Android3.2operating system as the software platform, to archive the demand of mobile entertainment and mobile office.The project uses a capacitive multi-touch screen as the human-computer interaction carrier; a shielding case is designed to improve the sensitivity and reduce interference from LCD, and further reduce interference through software to cope with the complex network environment. Large-capacity lithium polymer battery are used as the input of the power management system, designed DVFS system, and temperature sensor, gyroscope, E-compass and acceleration sensor to achieve a variety of rich multimedia applications. Two CMOS image sensors to be used for image acquisition, and reach the real time processing through Tegra2built-in graphics processing unit. A TD-SCDMA/GSM voice communication is designed over the Android system.The thesis presentation of mobile Internet terminal design has some special feature, for example,the system is highly integrated, content sharing, multi-touch sensitive, support3G dynamically loading characteristics and wireless display.
