The Research And Development Of PMC8241 Embedded System Board

The Embedded System Research is an important developing direction of the Computer Application. The Embedded System, who is being applied to the most of things around us, have a huge market.The PMC8241 Embedded System Board, which based on Motorola PowerPC 8241 processor and integrated 10/100M Ethernet and RS-232C interface. The OS is Linux, who has lots of benefits, such as open source code, apply and develop easily, many application programs. The embedded system have complete functions, small volume, low power and strong stability. In addition, it provides the standard industry interface. So it could be used at Switch, NC and other equipments.This paper will discuss the design and development of the Embedded System based on the PMC8241 Embedded System Board. This paper is a conclusion of the study and work in my graduate research stage.This paper consists of five chapters. The first chapter introduces the concept of embedded system. The second chapter introduces the produce of hardware system development. The third chapter introduces the design of software system, which includes the base software and the operate system. The fourth chapter introduces the debug method and environment. The fifth chapter introduces the Ethernet Swtich application of this embedded system and other appropriate applications. The last chapter summarizes all paperjjoints out the improvement for current implementation, and indicts the future directions of the system.
