Abstract

The embedded system can be defined as a special purpose system with a built-in computer, and has a wide variety of applications such as home appliances, office equipment, and weapon systems. A well-defined taxonomy in a specific field is advantageous for learning and education, however, the classification scheme for embedded systems is difficult to find. In this paper, we propose a taxonomy for embedded systems. First, the generalized structure of the embedded system was presented. And, it is divided into two parts: "firmware based" and "embedded OS based". In addition, according to the characteristics of embedded system applications, it is divided into two categories: "non-dependable" application and "dependable" application, which makes 4 planes. We describe the features of each quadrant and show that the classification is well suited by showing examples. Our taxonomy can be used to set teaching and learning methods of embedded systems.

임베디드 시스템은 컴퓨터가 내장된 특수목적 시스템으로 정의하며 가전제품, 사무기기, 무기 체계 등 매우 다양한 분야에서 사용된다. 특정 분야에서 잘 정의된 분류 기법은 교수 및 학습에 강점을 갖는데 임베디드 시스템을 위한 분류체계는 찾아보기 힘들다. 본 논문에서 우리는 임베디드 시스템의 분류체계를 제시한다. 먼저, 임베디드 시스템의 표준화된 구조를 제시한다. 이 구조에서 임베디드 시스템 응용들을 "firmware-based"와 "embedded OS-based"로 나눈다. 또한, 임베디드 시스템 응용의 특성을 기반으로 "고신뢰 응용"과 "일반 응용"으로 나누는데 그 결과 총 4 개의 영역으로 임베디드 시스템 응용을 나눈다. 우리는 각 영역의 특징을 제시하고 임베디드 응용들의 사례를 제시하여 우리의 분류체계가 적절함을 보였다. 우리의 분류체계는 임베디드 시스템의 교수/학습법에 잘 활용될 수 있을 것이다.
