Design Of Board Based On GS32I And Embeded Linux Transplant

Currently, the embedded system has broadly used in many fields such as industry control, the military national defense,electronic consumable ,communication and so on, but most of all application are based on embedded processor of foreign manufacturers. So useing the domestic chip in embedded realm are now becoming a urgent problem to be solved.The Godson's series processor is the first 32-bits CPUs of China,in which the characteristics of both the general cpu and the embedded cpu are considered. In this dissertation, taking the godson GS32I SoC processor as the core, we study how to design a small embedded hardware system, which is designed for the research in Embedded System and for the hand-held PC products also. Using this platform we can make the experiment of embedded algorithm by linking all kinds of peripheral, and this platform through simple modification can expediently be applied to the military, industry control, data acquisition and so on. It has the important meaning to use the national product in the embedded realm.The schematic diagram of the design is pictured with Orcad Capture and the Printed Circuit Board(PCB) is designed with PowerPCB.The embedded Operating System is the linux in the platform. Linux is an open source operating system which becomed more and more mature from 1990s,and be extensively concerned in the embedded realm. In this dissertation, it is discussed that how to analysis the linux kernel, how to cut and configure the linux operating system and how to boot the linux in the GS32I CPU. Finally the linux OS is embedded in the GS32I board and booted from the network or the DOM.
