Abstract:  

 Abstract:  Based on the research and successful implementation of the portable computer which uses the selfdetermination key technology productions such as the selfdetermination CPU, firmware and OS, this article summarizes the design and implementation of the portable computer’s hardware and software platform. It introduces the system architecture and the realization of the main function circuits. Furthermore, the loading of the selfdetermination firmware and OS and the matching of the I/O devices is described. Besides, this article gives a full description of the inner infrastructure, cooling, heavy reducing and structure reinforce. At last,
the sample model’s performance is tested, which includes integer and float calculate capablility, system response time, multitask data interactive capability and CPU processing capability.
