The Android Platform Intelligent Terminal System Design Based On Qualcomm APQ8064

Android is a Linux based open source operating system, now widely used in mobile phones, Pad handheld devices such as terminals. In the mobile Internet related areas, the development of the system showed a rapid movement. In recent years, due to strong market demand,the number of mobile Internet giants have set foot in Android mobile intelligent terminal equipment product development and production.The author has practised in the Communication Technology Shanghai Sheng internship,the company is well-known information technology solutions provider of intelligent terminals, using Qualcomm platform combines the latest Android development technology to provide customers with customized solutions of various types of smart terminals. Early in the2013, the company successfully design based on Qualcomm (APQ8064) quad-core terminal solutions. Based on this program, has completed the development and promotion of the market multiple terminal project.The topic of the Issue based D1mobile phone project, using its hardware system solutions to build the hardware platform and the underlying software system design based on the completion of the project the latest Android4.2designs. Mainly involved in the completion of the D1underlying system software system design, including the drive to achieve, hardware abstraction layer module features transplantation and commissioning work, combined with the actual needs, design a test application.D1software system for different hardware modules, the appropriate device driver model based design of the driver. Hardware abstraction layer and the underlying hardware can drive the expansion interface module encapsulation. This approach simplifies the porting Android system between different hardware systems. D1project commissioning process module functions were transplanted and adjusted according to the hardware features. D1software system test applications is optimized for specific modules designed to optimize，It can improve the performance of the final product to provide a stable protection.Currently the machine has received customer acceptance,related work is nearing completion, stable product prototype performance, user experience better.
