The Software Platform Design Of Embedded Linux-based Workstation

With the popularity of embedded system,a well-designed operating system has became an indispensable part of it. And an excellent Linux system, of which the source code is open, that befit it to be a embedded operating system.This paper will introduce the application of embedded system in the grain detecting and controlling system.The hardware platform is include in Micro Processor Unit MC68EZ328 which is the core of hardware platform, system memory device such as Flash and RAM, peripheral interface such as serial port interface, network device interface, CAN communication interface and man-machine interactive interface.The function of embeded Linux-based workstation is implemented by software. The driver software of peripheral device and application software to implement concrete function of workstation are included in software design.Then this paper introduce Micro Processor Unit S3C44B0X.Mobile Internet is one of the important high-end application of the embedded system. In order to make the embedded system access the internet to share the resource of the network ,a design and implementation of an Embedded Linux system based on a 32-bit microprocessor which can access the internet over GPRS wireless network is presented in this paper.The innovation of the embedded system consists in construction and function integration, standard application to industry communication protocol, standard of software interface and development of application software. It can be consulted and popularized by homogeneous system.
