Research On The Embedded Experimental Platform Based On ARM9

Embedded system is a special computer system.It is based on computer technology and takes the application as the first important thing, its software and hardware can be cut out, and it also is fit for application systems which have strict request with function,reliability,cost,power consumption and bulk。With the rapid development of Information and network,embedded system technology is widely used in all kinds of fileds,for example,mobil communicaion equipment, Intelligent appliance,automotive electronics,industry control,digital entertainment and so on.As the Micro-processor based on ARM core has been playing more and more important role in the embedded system field,studying ARM based embedded system has important sense of theory and practice.The paper mainly involves the designing of the embedded development platform , First, we put forward the needs analysis report based on our platform's applicaion fields. We choose the Samung company's S3C2410 micro-processor as the platform's core processor after analyzing the CPU capability,power consumption,interface and cost factors,which is based on ARM920T core.Then we design the general layout of the hardware platform and implement all the modules including the CPU and the memory,the audio device,the CAN communicaion device,the power,the network card etc.We also discussed the anti-jamming issue theoretically and practically from various aspects.We design the layout of the software system based on the hardware platform and migrate the BootLoader,the Linux kernel,the file system the CAN device's driver and other moudles after analyzing each one's principle or structure.Finally,we provide the test result of the system.The result shows that the whole design satisfied all requirements.
