Design And Realization Of Embedded System Development/Experiment Platform Based On ARM7 Kernel

With the rapid development of embedded application technology, embedded systems are widely used in all aspects of human life. As demands of embedded talent increasing in society, many universities have set up many courses about embedded applications.As the subject highly comprehensive, it requests higher level in programming and hardware knowledge of students, and there should have corresponding experimental platform. View of the current situation, this paper designs the hardware of multifunctional embedded system experimental platform with ARM7 processor. Selecting S3C44B0X as the core of system processor and designing the circuit of each module, it can achieve an embedded experiment platform with complete function and assistant education.The design of system includes the power circuit and reset circuit of ARM7,circuit design of storage systems, SIO communications, keyboard, Nixie tube circuit, touch screen and LCD interface circuit. With the support of operating system, it compiles the interface drivers and achieves loading of Bootloader. This system is an experimental platform based on S3C44B0X processor, which is able to quickly input, store and display, meeting the needs of embedded teaching experiment, at the same time as an embedded development platform.
