Based On The Arm Platform Of Tax Pos The Realization Of The Boot Loader

After many kinds of embedded products appeared and mobile products became more popular, the embedded system has become into a hot spot of research. It is not a new technique which appeared recently. Because of the popularity of the micro-electronics technique and the computer technique, the functions of the embedded product become more and more powerful, and it has been applied more and more extensive. This kind of technique has attracted more and more people's attention. It has grown more strictly demanding in the size, cost, power, reliability of software and hardware. The functions of the embedded product become more and more powerful, and the actualization of the embedded product becomes more complicated and difficult. So, the reliability, transplantability, configuration and customization of the embedded product become more important.At the mean time, it puts forward higher request in processor capability. Now, many semi-conductor suppliers produce ARM processor, and the technique of ARM has occupied to be in the lead position in the embedded microprocessor realm. It has a balance design, which regards the reduced instruction frame as principle but do not abandon complex instructions. So, ARM processor can obtain high-performance, at the same time it is low-power processor. This paper mainly introduces the design and actualization of Boot Loader of JavaPOS machine based on the ARM processor hardware platform. Boot Loader is a section code of embedded system which carries out before OS, and its primary function is initialization and loading OS.About the design and actualization, this subject is not limited at the given JavaPOS machine and the primary function of Boot Loader. The purpose of this project is actualizing Boot Loader as a more complicated system besides the primary function. It has convenient configuration and transplantability, and it can be transplanted conveniently to other...
