| With the rapid development of computer technology, embedded system is moreand more widely used. By now, embedded computer system is much more thancommon computer in quantity, there are about 5-10 microprocessor in peripheralequipment of a computer. At the mean time, lots of network equipments become thenew application environment of embedded system since the progressivelydevelopment of network technology. The cheap and powerful microprocessors andvarious kinds of peripheral equipments have made the hardware frames of all kinds ofembedded applications stable and reliable. Since 1990s, ARM which is 32-bitembedded RISC microprocessor, has been spread to the range of the world, andoccupied in the field of application of low consumption, low cost and highperformance embedded system.Because its excellent kernel design and application performance, Linux is runningon many kinds of hardware, Linux also owns other merits such as its free source code,it's inherit networking functions and its modularization design in kernel. ThereforeLinux is very suitable to be the operate system of embedded system. uClinux is abranch of embedded Linux. And it is designed for NO-MMU CPU.In this thesis, the embedded Linux system based on ARM has been developed.The embedded hardware system was designed taking Samsung ARM7TDMI CPU asthe core. And a small uClinux system is embedded into this hardware system. Variouskinds of application in uClinux system can be developed. This thesis introduces oneapplication-embedded web server and its protocol-HTTP. We have already solved theproblem of developing ARM and researched the project of developing ARM. Theimportant thing is that we successfully solved the difficulties of porting uClinux intoARM hardware platform. This provides with a higher practice and research value inthe field of studying embedded system. Our embedded system has the characters oflow cost and high efficiency. At least, a sum-up and prospect of some other usage ofLinux embedded system are given. |
