The United States is having a technique from Embedded SW fields of the best in the world, followed by Europe, Japan and Korea. Specially, Korea and Europe technical power is highly estimated and is before Japan from intelligent SW fields. The technical level of Korea compares with advanced countries and it is equal or excellent in application and part field in service SW. In the paper we look at the Embedded SW technical trends and technical level and difference of domestic and foreign among the counties. And we devise a stratagem for the promotion strategy of embedded SW industry.

The development process of Embedded Software (SW) is gathering interest due to the increased importance of SW in mobile products. According to tough competition and the growing size of the Embedded SW, there is a demand for a new effective way to improve the SW development process, based on customer and market quality aspects, rather than focusing on defect removals in individual SW modules. We review 103 SW improvement projects from the area of mobile phones in order to check the effectiveness of Six Sigma which is the standard for the process improvement statistical tools and methods.

스크래치박스를 이용한 임베디드 응용 소프트웨어 통합개발환경은 응용 프로그램 개발자들에게 타겟종류에 관계없이 일관된 개발 환경을 제공하는 것을 목적으로 하고 있다. 응용 프로그램 개발자들은 개발하고자하는 응용 프로그램의 실행환경(타겟)에 따라 개발 및 실행 환경 구축에 많은 시간을 소비한다. 따라서 이러한 개발 및 실행 환경 구축을 용이하게 해주는 통합개발환경을 응용 프로그램 개발자들에게 제공함으로써 응용 프로그램 개발 기간을 단축시킬 수 있다. 또한 다양한 실행 환경을 제공함으로써 응용 프로그램 개발자들이 자신이 개발한 응용 프로그램을 적절히 테스트 해 볼 수도 있다.

A wearable computer has appeared as the next generation computer with the development of embedded system technique in our country, although it has not been applicable well since the hardware and software capabilities are limited for multimedia service. We have implemented a MPEG-4 video player to provide with such multimedia application service using the embedded systems. This paper illustrates the development of MPEG-4 video player operating on the wearable computer named WPS(Wearable Personal Station), the wristwatch PC developed at ETRI.

IT related services are available in the shipborne and maritime area. As their service requirements are requested diversely, the safe and reliable embedded system based device needs increase. There are two categories in embedded system : communication/control system and various user interface needed service system. In this paper, we propose the classification of embedded system in the shipborne and maritime area and provide two reference embedded system platforms and their components. One is low-level embedded reference platform of communication/control system and the other is high-level embedded reference platform of user interface oriented system.

Rapid increase of embedded systems in electronic and mechanical control systems requires reliable and error-free embedded software. State-based testing methods like FSM are usually used to assure the reliability of embedded software. However, because of possibility of explosion of test cases, only partial test cases are considered in practical tests, which cannot guarantee that all the possible errors are investigated. This study proposes a test procedure based on failure mechanisms that may occur in embedded systems, which can not only assure that certain kinds of possible errors are detected but reduce the testing time. The proposed procedure is applied to vehicle air control system.

As the complexity of SoC (System-on-Chip) design increases dramatically. traditional system performance analysis and verification methods based on RTL (Register Transfer Level) are no more valid for increasing time-to-market pressure. Therefore a new design methodology is desperately required for system verification in early design stages. and hardware software (HW-SW) cosimulation at TLM (Transaction Level Modeling) level has been researched widely for solving this problem. However, most of HW-SW cosimulators support few restricted ion levels only, which makes it difficult to integrate HW-SW cosimulators with different ion levels. To overcome this difficulty, this paper proposes a multipurpose framework for HW SW cosimulation to provide systematic SoC design flow starting from software application design. It supports various design techniques flexibly for each design step, and various HW-SW cosimulators. Since a platform design is possible independently of ion levels and description languages, it allows us to generate simulation models with various ion levels. We verified the proposed framework to model a commercial SoC platform based on an ARM9 processor. It was also proved that this framework could be used for the performance optimization of an MJPEG example up to 44% successfully.
