Abstract: The form and function of the handheld devices is variety. Each product will need to develop a new re-development, even if the feature is very close. We propose a scalable handheld devices design scheme based on PXA322 embedded processor, describe the handheld devices’ each hardware circuit interface module in detail, include: the handheld devices’ basic system module formed by the CPU(PXA322), SDRAM and FLASH; the communication system interface module formed by DM9000 etc; human-computer interaction interface module; power management module etc, and we also complete the corresponding operating system migration and the system’s functional integrity testing work on the hardware system. The board has a high versatility, the cutting of its hardware and software is flexible, it also increases the development efficiency of the handheld devices.

Abstract: Combining with the function and characteristics of the PXA320, In view of the current existing problems of the handheld devices power and demand of high-end hand-held devices market.Design a scalable application platform for embedded general-purpose handheld devices based on PXA320 processor. First, introduces the system's hardware platform, optimizing the external interface circuit, and then discusses the software architecture of Linux operating system, On this basis, testing the data of core board by developed the corresponding application, the results show that: this platform has good reliability, stability and maintainability and provide powerful support for the development of high-end handheld device.
