Operating System Configuration Based On SOPC Technology Research

Tax orderly development of the national protection of economic, political, stability of the mandatory management measures, strict, accurate, and timely collect taxes in full, and will reflect the interests of the country. Enhance national tax control, security reasonably orderly competition is to establish the basic requirements of the national tax system. National tax authorities has been committed to tax according to law, according to tax law, is also in constant and tax evasion and to combat tax evasion behavior, but the lack of data is caused Fiscal first-hand the intensity of tax administration can not keep up the important reasons one.In GB18240.7 prototype system development project, due to the commercial circulation system has been established based on the work of the business local area network server environment, the financial server and a lot of POS , the solution adopted on this basis Fiscal added tax control server and network device, in the sales process of printing a small ticket tax to total tax control. However, the existing network of tax control device with ARM architecture, design is more fixed, change is not flexible enough, the system life cycle is shorter. The subject of FPGA-based SOPC design network technology tax control device, you can achieve high flexibility and avoid the risk of outdated design, greatly improving the equipment life cycle. And the use of IP reuse ideas can also shorten the development cycle, reduce development costs and enhance market competitiveness.This thesis studies the network tax controller hardware engineering structures and the operating system migration and configuration. First discusses the research background of the subject and research status. Then the network tax controller device solutions and selection, including the SOPC system construction program and embedded operating system program. The next is the focus of the content of this article, that is, the specific project implementation process, which includes system definition, IP core and system components to add, engineering and programming to download and compile mCLinux operating system configuration process migration. Finally, tax control device from the network application layer aspects are given for the serial communication module and data acquisition module application.This issue can be e-information technology development and the current medium and large shopping malls, supermarkets, chain stores combined business forms, tax authorities will carry out duties according to law, according to tax law play a positive role in promoting.
