[Abstract]:From consumer electronics to industrial equipment, embedded systems have penetrated into every corner of our daily life. The application software and the operating system of most embedded devices are closely combined. It is precisely because of the powerful function of the embedded operating system that the embedded system can play such a great role. So it is very necessary to build embedded operating system on embedded system. FPGA and arm are two different fields of embedded system, although many general processing uses arm processor, Moreover, arm is also very mature in the support of embedded operating system. But FPGA can be applied more widely and more flexible, so it has great practical significance to build embedded operating system on FPGA. Due to the reasons of open source, stability, high performance, wide support and so on, Linux system is becoming more and more popular in server and PC, so it is natural to take Linux system as the first choice of embedded operating system. This paper introduces the system on a Programmable Chip SOPC (SOPC) and its development process. Through SOPC technology, the hardware configurable embedded system can be built on FPGA, which has the advantage that the conventional embedded system does not. The porting method of embedded system operating system based on SOPC is deeply studied, and the related environment is configured. At the same time, the corresponding software package is modified, and the embedded Linux operating system image is compiled. Can be implemented on the FPGA development board SOPC embedded system normal operation. On the basis of the above work, the SOPC system is applied to the information terminal of the bus station in the intelligent bus system, and a prototype system is built. In this paper, the overall design of a system is presented, which mainly includes the function modules of multi-channel connection, authentication, data receiving, peripheral display and alarm, and the function and detailed design of each component module of the system. The algorithms of accessing multiple connections and connection authentication are studied, and the implementation of the system is given. The simulation test environment is mainly composed of bus station information terminal, vehicle terminal and bus line central server based on SOPC. A corresponding test program is developed to test the function of the bus station information terminal system. The test results show that the information terminal system based on SOPC can meet the demand of intelligent bus system.
