It seems necessary to have a new methodology to develop the complex embedded system in a short time with a small amount of money and secure the reliability of products. For this in this study, the investigator presents the state-of-the-art technology with which the limitation of physical prototyping and virtual prototyping can be overcome. Also as a developing methodology of the em-bedded system in which the new technology is applied, the investigator suggests a new methodology of developing process for the integrated design, integrated simulation, and debugging of the physical prototyping and the virtual prototyping.

A prototyping means the way to improve system better from add, modify and delete in the middle of System's working with making model of system simply to offer users in the first develop which the first model is similar in the real model. but there are virtual prototyping and real prototyping in the skills of prototyping but there is some limitation for simulating variety and detail product in the real prototyping and hard to make a simulation of environment elements of the target model in the virtual prototyping. Integrated prototyping system is improved to make up for their defects of environment in the real or virtual prototyping. In this theory, to have flexibility, reusability, scalability and accessibility we build environment of integrated prototyping improvement which is based on component with linkage method between virtual and real.

Since interactive systems that the user interaction is important factor can be very complex, its design process may have various testing and feedback based on continuous prototyping. The prototypes in this process function as medium to explore design problem and communicate opinions with another expert of project team. So prototyping strategy may be needed to enhance the design quality by focusing on the goals of project. This study clarifies critical issues around the prototypes and characteristics of interactive system to understand broad meaning of prototypes. And prototype model proposes as a framework for establishment of prototyping stategy.

Recently, there are many embedded system prototyping tools for helping embedded system designers to trial their product before it releases to the market. A prototype is very important for early embedded system design to grasp the desire functions, to get a good performance, to create delightful user interface, and to increase the valuable of the product. Prototyping tools can be classified by three categories: Physical, Virtual and Modeling prototyping. The integration of these prototyping tools becomes valuable for speed up time-to-market and for decrease design cost when design embedded system. The problem comes up because these tools sometime do not provide an instrument for communicating each other. In this paper, we propose a flexible and reusable mechanism for integrate these tools base on JavaBeans and ActiveX technology. We show how this mechanism can be employed in various prototyping tools.

프로토타이핑이란 개발자들과 사용자들의 의사소통상의 효과를 증진시키기 위하여 취하는 시스템개발상의 기법이며, 이러한 프로토타이핑에는 가상 프로토타이핑과 실물 프로토타이핑이 있다. 본 논문에서는 기존의 실물/가상 프로토타이핑 연동 기법을 개선해서 오브젝트 기반의 임베디드 시스템 통합 프로토타이핑 개발 환경을 구축하였다. 이러한 새로운 임베디드 시스템 개발 환경을 구축함으로써, 재사용성, 유연성, 확장성 그리고 편리성을 가질 수 있다.

In the virtual prototyping environment, we can simulate details of a target model using many components and libraries provided in advance on a computer. The real prototyping environment provides the test simulation environment as a real product, but we can't do a detailed simulation of a real product in the virtual prototyping environment, and we can't do various simulations in the real prototyping environment. So, we made a integrated prototyping environment for linkage of the two types of prototyping environments. Also, in this paper, we developed the integrated prototyping environment based on objects. By this kind of embedded system development environment, we can have the advantages as reuse, flexibility, scalability, and more convenient of product making.

기존 통합 프로토타이핑 시스템은 가상과 실물 프로토타이핑간의 단순 연결을 통하여 시뮬레이션만 하는 것이 한계였다. 본 논문에서는 그러한 통합 프로토타이핑 기술을 개량하여 GUI기반의 가상 프로토타이핑 개발도구에 컴포넌트형태로 넣어서 드래그엔드랍을 통한 통합 프로토타이핑 시스템 환경을 구축하는 것에 대해서 보이고 있다.

The development of digital technologies transforms the design targets, characteristics of the targets and the role of designers. The paper highlights the role of prototyping in the interactive digital product design process and presents the survey and analysis of prototyping tools that can be used by designers in designing such products. From the review of tools in design related fields. the classification framework for the tools were presented. The framework has the criteria of the fidelity of prototypes, the stage when the prototyping is used, and design targets. Based on the analysis, the implications for using the tools are suggested. They includes that prototyping is important in the concept stage for designers and different tools and methods are to be applied according to design targets and objectives. Prototyping tools need to support exploring design concepts without being constrained by implementation technologies The collaboration with other professionals can also help effective prototyping. Existing tools familiar to designers can be effective platforms for the new design problems. The results can be guidlines with which designers choose more appropriate prototyping tools when they face new design problems. It also make practical contribution in improving design efficiency and design education for interactive product design projects.

프로토타이핑 시스템 설계에서 프로토타이핑은 실제 모델과 같은 초기 모형을 뜻하는 것으로 개발 초기에 시스템의 모형을 간단히 만들어 사용자에게 제시하여 사용자로 하여금 실제 작동시켜 기능의 추가, 변경 내지 삭제를 요구하도록 하여 시스템을 점차적으로 개선시켜 나가도록 하는 방식을 말한다. 가상 프로토타이핑은 임베디드 소프트웨어 개발 초기단계에서 사용자 혹은 의뢰자의 요구사항들을 효과적으로 추출할 수 있도록 고안된 시스템 요구 및 제약조건 추출 방법론이다. 본 논문에서는 가상 프로토타이핑 기법을 이용하여 멀티미디어 플레이어의 다양한 기능을 시뮬레이션 할 수 있는 가상 프로토타입을 설계 및 구현한다.
