Abstract

RT-eCos 3.0 is a micro-sized embedded real-time kernel that has been developed based on the open source eCos 3.0 to support the basic task model of the well-known distributed real-time object model, TMO(Time-Triggered Message-triggered Object). In this paper, the design and implementation techniques of the RMMC(Real-time Multicast & Memory replication Channel) that is a standard distributed IPC model of the TMO is described based on the RT-eCos 3.0. And the support technique of the global time for using the same time in a distributed environment using the RMMC is also described. The developed global time based RMMC supports highly abstracted distributed IPC environment in a wide area distributed computing environment with the RT-eCos 3.0.

RT-eCos 3.0은 대표적 분산 실시간 객체 모델인 TMO(Time-triggered Message-triggered Object)의 기본적 태스크 모델 실행을 제공하기 위하여 공개소스 eCos 3.0 기반으로 개발된 초경량 경성 실시간 임베디드 운영체제이다. 본 논문에서는 RT-eCos 3.0에서, TMO 표준 분산 IPC인 RMMC(Realtime Multicast & Memeory replication Channel)를 지원하기 위한 설계 및 구현에 대해 기술한다. 또한 RMMC를 사용하는 분산 노드에서 동일 시각을 사용하기 위한 글로벌 타임의 지원 기술에 대해서도 기술한다. 개발된 글로벌 타임 기반의 RMMC는 RT-eCos 3.0과 함께 광역 분산 컴퓨팅 환경에서 동일 시간기반으로 추상화된 고급의 분산 IPC 환경을 제공한다.
