Research On The Application Of Ethernet In Embedded Systems

Network storage is one of the most popular technologies in high-tech industry in recent years. With the development of the computer and network technology, more and more information must be handled as data which is stored in the computer. This data may need to be saved for a long time and can be retrieved quickly and easily. The popularity of the information technologies, such as e-commerce and e-government, requests the data storage technology to have much more capacity, speed and security. Storage technology also develops from local storage to network storage.ARC810 processor is a SOC chip based on LEON2 core and it is produced by ACARD Technology Corporation in Taiwan. This paper mainly implements the bottom part of the Yizhan (Xiamen) electronic Company's network storage project. The mainly work consists of the transplant of RTEMS to ARC810 board, implementation the driver of the Rhine fast ethernet network adapter under RTEMS. In addition, this paper designs and implements a cross debug tool based on ethernet in order to fix the deficiencies of the ARC810's current cross debug tool.The characteristics and innovations in this thesis are as follows:1) implement the driver of the Rhine fast ethernet network adapter under RTEMS on ARC810 board, also test and optimization the driver.2) design and implement a cross debug tool based on ethernet to fix the deficiencies of the current tool of ARC810.
