초록

임베디드 소프트웨어는 탑재될 하드웨어 아키텍처에 매우 의존적이기 때문에 플랫폼 특성을 고려한 소프트웨어 설계가 이루어져야 한다. 본 연구에서는 MPSoC(Multi Processor System On Chip)용 플랫폼에 탑재될 임베디드 소프트웨어의 PIM(Platform Independent Model)을 PSM(Platform Specific Model)에 매핑하기 위한 기법을 제안하고, 매핑 결과에 대한 시뮬레이션을 통해 매핑 기법의 유효성을 검사하였다. 제안하는 방법은 UML(Unified Modeling Language) 기반의 객체지향 모델로부터 태스크를 도출하여 이 기종의 하드웨어 컴포넌트로 구성된 MPSoC 플랫폼에 할당하기 위한 것으로써, 할당의 정확성 및 신속성과 소프트웨어 병렬성을 극대화 할 수 있는 장점을 제공한다.

Since embedded software is very dependent for target hardware architecture, characteristics of the platform must be considered when designing the software. Furthermore, MPSoCs consists of heterogeneous hardware components that are specified in micro level. Thus mapping of embedded software for MPSoCs should be considered the characteristics. In this paper, we provide an approach to automatic mapping PIM (Platform Independent Model) of an embedded software to PSM(Platform Specific Model) for MPSoC(Multi Processor System On Chip) and verify its effectiveness with simulation. In the proposed approach, tasks are derived from an object oriented model based on the UML (Unified Modeling Language). And then the types of the derived tasks are identified. With the identified types and inter relationship between tasks, the tasks are assigned to appropriate heterogeneous hardware components. We expect that the approach improve accuracy of the assigning and concurrency of the deployed software.
