Compiler development projects, which are designed and taught in compiler course, allow students to practice and absorb valuable amount of experience and techniques in developing compilers. However, both instructors and students face difficulties as they are often limited by insufficient hands-on time during course of an academic year along with a relatively high level of technologies involved when dealing with compilers. As well, most compiler's target systems use interpreter-based technologies which are rather limited in drawing student's attention. As a result compiler courses often end up being more of a theoretical course than practical. This paper presents a new integrated development environment (IDE) that will help overcome aforementioned difficulties and allow students to obtain both theoretical and practical knowledge more efficiently. The development environment includes a reference compiler with $Mindstorms^{(R)}$ NXT Robots as the target system, compiler development tool, target language test tool, and code generation visualizer. It is developed as a plug-in for the popular Eclipse IDE which enables easy access and great expandability. This integrated development environment allows students to understand compilers better and start their development faster.

Compiler and language implementation courses have long been recognized as an important subject in Computer Science curricula. It is because not only the knowledge for a compiler plays important roles in understanding programming languages and systems but compiler technologies can be used in many applications. However it requires much effort to teach effectively it due to limited resources and time restriction. We present a compiler teaching model using Edu-IDEC which is a development environment of educational compilers. Edu-IDEC is a tool on the robot platform. It uses the Eclipse plug-ins and has functions like compiler developing tools, a reference compiler, visualization tool of syntax tree, visualization tool of object language, NXT robot controllers, and its simulator. We also present the evaluation results for our model by applying it to an actual class.

This paper presents the implementation of RFID EPC global network educational system based on using 900MHz air interface between the reader and the active tag. The software of reader and the active tag is developed on embedded environment, and the software of PC controlling the reader is based on window OS operated as the server. The ATmega128 VLSI chip is used for the processor of the reader and the active tag. As the development environment, AVR compiler is used for the reader and the active tag of which the programming language is C. The visual C++language of the visual studio on the PC activated as the server is used for development language. Main functions of this system are to control tag containing EPC global Data by PC through the reader, to obtain information of tag through the internet and to read/write data on tag memory. Finally the data written from the active tag's memory is sent to the PC via the reader as "read" operation and compare the received data with one already sent to the tag. Software implementation of 900MHz EPC global RFID educational system is done on the basis of these functions.

This paper presents the development of RFID educational system based on using 900MHz air interface between the reader and the active tag. The software of reader and the active tag is developed on embedded environment, and the software of PC controlling the reader is based on window OS operated as the server. The AT89C51ED2 VLSI chip is used for the processor of the reader and the active tag. As the development environment, Keil compiler is used for the reader and the active tag of which the programing language is C. The visual C language of the visual studio on the PC activated as the server is used for development language. To verify the function of the system, PC gets the tag's identification number through the reader and send the data to with the active tag memory a certain contents as "wite" operation. Finally the data written from the active tag's memory is sent to the PC via the reader as "read" operation and compare the received data with one already sent to the tag.

This paper has designed and realized educational ZigBee equipment befitting to the USN environment. In addition, this study has enabled users to exercise operation process for software technology education and to propose software design methods in the process in the USN environment through practice equipment for ZigBee education. As for the development environment of system, Atmega128 process of Atmel is used for CPU; AVR compiler for the debugging environment; C language for firmware development language; and C++ for application program. The system operation process is initiated by coordinator's sensing information reading order from the hyper terminal through a server through the Internet or directly connected; and then delivering it to a terminating device by using ZigBee technology. The terminating device delivers various sensing information to the coordinator which delivers it to a server through the Internet or to a HYPER terminal directly connected to the coordinator. As for the educational course, it is about practices on such ZigBee operation process and relevant programing skills. Regarding it, the communication between coordinator and terminating device is designed by utilizing physical layer of ZigBee protocol, MAC layer and network layer while the communication between server and coordinator is designed by proposing an independent protocol on TCP/IP socket and the protocol processing procedure during sensing data delivery is verified by interpretation.

By the use of open source and 16bit Microcomputer, IDB(Integrated Development Board) for embedded technical education was designed and developed. Based on 16bit MCU H8/300H, LED, LED Matrix, motors, sensors and various I/O circuitry, and the connection to a computer via the SCI, and $16{\times}2$ character LCD was designed and implemented on IDB. In addition, the software development environment was build by the assembler and H8 C compiler which is provided to the open-source software. And memory expansion was considered to include TRON(Real time OS) and uClinux. To verify the developed board, IDB was fabricated by PCB machine, and the fuction was confirmed by the basic I/O control program.
