하드웨어 검증은 하드웨어 디자인 단계에서 필수 요소이다. 하드웨어 검증은 시뮬레이션 방식과 에뮬레이션 방식으로 나뉘며, 상대적으로 빠른 에뮬레이션 방식을 이용해 최종적으로 하드웨어를 검증한다. 하지만 에뮬레이션 방식 역시 실제 하드웨어의 동작과 비교하면 상당히 느린 편이다. 본 연구는 보다 빠른 에뮬레이션이 가능한 Xilinx의 하이브리드 에뮬레이션 디바이스 Zynq의 성능을 정량화하여 에뮬레이션 장비와 실제 하드웨어 장비의 성능을 비교 및 분석한다. Zynq의 비교 대상으로는 이와 유사한 하드웨어 구조 및 사양을 가진 상용 디바이스 Tegra3를 비교하였다. 실험 결과 Zynq는 Tegra3에 비해 벤치마크의 수행에 있어서 상대적으로 낮은 성능을 보였다. 하지만 Zynq는 에뮬레이션 환경인 것을 감안하면 병렬성이나 벤치마크 실행 속도 측면에서 기존의 에뮬레이션 환경보다 높은 성능을 보여 주었다.

There is a lack of user centered design methods that support effective collaboration between designers and end-users for designing hardware and software integrated digital products. This paper presents the application of Collaborative Design and a new collaborative design prototyping tool for interactive digital product design projects. The tool consists of STCtools(State Transition Chart tools) software, hardware modeling materials, and physical interface toolkits for integrating software and hardware. STCtools allow users to create and edit States, to compose Events describing transitions between States, and to run intermediate or final results of STC. Using the hardware modeling materials and the physical interface toolkit, designers and end-users can collaborately examine the hardware and software integrated concepts in an early stage of the design process. Three collaborative design workshops of designing a portable digital guide for a theme park were accomplished to examine the feasibility of the tool. The results suggested that the tool supported iterative concept development and interactions between designers and end users. Although several user interface problems of STCtools were identified, the participants gave positive feedback on the role of the tool in collaborative concept generation and deployment. It is expected that the results of this study contribute not only to the collaboration between designers and end users, but also to the collaboration between designers, and between designers and other professionals.

본 논문에서는 임베디드 소프트웨어 개발 시 .Net Micro Framework를 이용하여 디바이스들의 통신 인터페이스를 소프트웨어 개발자가 좀 더 간단하게 코딩 가능하게 하며 소프트웨어 개발자가 이를 디자이너를 이용하여 그래픽하게 에뮬레이터를 디자인할 수 있도록 임베디드 에뮬레이터 생성 방법을 제시하고 디자인 된 에뮬레이터를 기반으로 자동으로 코딩 없이 에뮬레이터를 생성하는 프로그램을 프로토타이핑 한다. 이때, 소프트웨어 개발자가 그래픽하게 생성한 에뮬레이터 디자인으로 하드웨어 개발자와의 의사소통이 보다 원활해질 수 있다. 또한 본 논문에서 제시하는 임베디드 에뮬레이터 생성 프로그램을 이용하면 추가적인 코딩 작업 없이 디자인 된 에뮬레이터를 기반으로 에뮬레이터가 자동 생성된다. 이로 인하여 .NET Micro Framework에서 제공하는 확장 가능 에뮬레이터와 달리 에뮬레이터를 생성하는데 시간과 노력을 절약할 수 있다. 또한 기존의 개발 과정에서는 기계가 모두 준비되어야 테스팅이 가능했던 것과 달리 기계 없이 에뮬레이터로 테스팅이 가능해짐으로써 개발 기간을 단축시킬 수 있다. 임베디드 에뮬레이터를 이용하면 하드웨어와의 통합 테스트에서 버그의 원인이 하드웨어적인 결함인지 소프트웨어적인 결함인지를 판단 가능하게 하여 디버깅이 용이하게 되며 실제 동작과 원하는 동작을 비교해 볼 수 있다.

This Research suggest that key features of lighting simulation and intuitive theaterical design method can unify single system. It can produce the virtual scene of stage which is able to predict the number of lighting box and design budget. the final goal of this research is unifying lighting and stage design into on single system.

In this paper, we analyze the structure of TV video software, one of the warship combat management system software, and propose a standard architecture that minimizes software modification due to the discontinuation replacement of warship hardware. The class structure was newly designed to minimize the class modified when replacing the warship hardware by separating the variable elements and common elements of TV video software through FORM(Feature-Oriented Reuse Method), the common part that communicates with the warship combat management system and displays the TV screen and the variable part that communicates between the operator and the TV camera. In addition, the Strategy design pattern is applied to efficiently add and modify classes that directly use hardware-dependent APIs when replacing hardware discontinuation, and to make both discontinued and replacements available software. Finally, the reliability testing time and functional testing time of the existing TV video software and the proposed software were measured and compared, and finally, it was confirmed that the hardware discontinuation replacement cost was reduced.

진화 하드웨어(Evolvable Hardware: EHW)는 환경에 적응하여 스스로 하드웨어 구성을 변경할 수 있는 하드웨어로서 최근에 많은 관심과 함께 연구가 이뤄지고 있다. 하지만, 하드웨어의 복잡도가 증가할수록 진화를 위해 탐색해야 하는 해공간의 크기가 기하급수적으로 증가하기 때문에 아직까지 복잡한 하드웨어에 대해서는 좋은 활용방안을 찾지 못하고 있다. 이 논문에서는 이런 복잡한 하드웨어를 모듈별로 나눠서 진화시키는 방법을 제시하여 좀더 효율적인 진화의 가능성을 보인다. 기존에 주로 사용되던 회로 진화 디자인과 이를 모듈별로 나눠서 진화하는 방식을 실험을 통해 비교하고, 효과적으로 진화시간을 단축할 수 있음을 보인다.

The aim of this research is to investigate the difference in the capturing opportunities for each type of venture companies in the industry undergoing competition of a dominant design and then figure out the reason why they can be successful. Existing studies on venture companies are focused on the way to enhance a firm's competencies by acquiring and combining its resources. However, it is important for startups which have a lack of resources and capabilities to capture the opportunity to survive by understanding a changing environment. This study is focused on opportunity capture and strategic response to a changing environment and attempts to select and observe startup companies which are able to capture the opportunity and enter the market in the industry undergoing dominant design competition. In order to find out its difference in different types of business, we select one case from hardware startups and the other from software startups. According to the result of this study, the hardware startup focuses on market extension by lowering their prices and the software startup strives to induce more users to participate by the universalization of enabling technology so as to extend and standardize their technology in the environment undergoing dominant design competition. This feature of environment leads the difference in the approach for successfully capturing opportunity and thus hardware firms need to recognize the opportunity with profit potential from relationship with a number of cooperative firms while software firms need to identify the opportunity for extension of enabling technology which can be used by many users.

Until recently, ind ustrial designers designed the product packaging of Eletronic Media, and userInterface designers focused primarily on software design, But as computer related technology continues to evolve, this distinction has become ambiguous, As a natural consequence of these trends, industrial designers are getting more involved in user-interface design to develop interactive objects, Moreover, In the future, the whole Information of a product whIch means product packaging, marketing, training matenals, support as weIl as hardware and software will be regarded as a product, and user's entIre expenences including the material elements of product will be taken for the factors of user interface to expand the category of user interface design. The importance of interface design and its applications within industrial design has been stressed in the recent years, However researches on practical process in interface design developments have been rarely established. This paper aims to develop the interaction design process for the useful user-interface design by theoretical study and actual analysis of user-interface design.

It had been longer that the design mock-up was made mainly in order to test products. These days, it seems to be main stream that the working mockup is done because designers consider not only the design but also usability. In this study, the modular hardware toolkit, complimentary with Adobe Flash, was developed so that it solves the problem, the electronic hardware which the designers should struggle to make by themselves. This result thing could help the time of the design process to be short and contribute to make robust system rapidly.
