  • The object-oriented(00) distributed real-time(RT) programming movement started in1990's and is growing rapidly at this turn of the century. Distributed real-time simulation is a field in its infancy but it is bounded to receive steadily growing recognition for its importance and wide applicability. The scheme is called the distributed time-triggered simulation scheme which is conceptually simple and easy to use but widely applicable. A new generation object oriented(00) RT programming scheme is called the time-triggered message triggered object(TMO)programming scheme and it is used to make specific illustrations of the issues. The TMO structuring scheme is a general-style components structuring scheme and supports design of all types of component including hard real time objects and non real time objects within one general structure.

  • Real-time(RT) object-oriented(OO) distributed computing is a form of RT distributed computing realized with a distributed computer system structured in the form of an object network. Several approached proposed in recent years for extending the conventional object structuring scheme to suit RT applications, are briefly reviewed. Then the approach named the TMO (Time-triggered Message-triggered Object) structuring scheme was formulated with the goal of instigating a quantum productivity jump in the design of distributed time triggered simulation. The TMO scheme is intended to facilitate the pursuit of a new paradigm in designing distributed time triggered simulation which is to realize real-time computing with a common and general design style that does not alienate the main-stream computing industry and yet to allow system engineers to confidently produce certifiable distributed time triggered simulation for safety-critical applications. The TMO structuring scheme is a syntactically simple but semantically powerful extension of the conventional object structuring approached and as such, its support tools can be based on various well-established OO programming languages such as C++ and on ubiquitous commercial RT operating system kernels. The Scheme enables a great reduction of the designers efforts in guaranteeing timely service capabilities of application systems

  • 본 논문에서는 실시간 객체모델인 Time-triggered Message-triggered Object (TMO)를 사용하여 분산 실시간 멀티미디어 스트리밍 서비스를 효과적으로 개발 할 수 있는 새로운 소프트웨어 프레임워크와 스트림 동기화 메커니즘을 소개한다. 본 프레임워크의 목적은 개발자로 하여금 복잡한 실시간 멀티미디어 스트리밍 서비스를 쉽게 설계하고 적시 스트리밍 기능들을 제공하는데 있다. 이를 위해서 본 프레임워크는 Multimedia Streaming TMO, MMStream TMO Support Library 그리고 TMO Support Middleware로 구성된다. 특히, MMStream TMO와 동기화 기법이 제공하는 time-trigger번 특성은 QoS 보장이 어려운 통신 채널과 시스템 환경에서 불규칙한 미디어 데이터 전달 및 처리하는 역할을 실시간으로 수행한다. 결론적으로 본 논문에서 제시한 프레임워크의 적시 서비스 능력은 향후 실시간 멀티미디어 스트리밍 서비스 개발에 기여할 것으로 기대된다.

  • 객체 지향 실시간 통신 분산 프로그래밍 구조를 구체적으로 나타내기 위해 시간 구동과 메시지 구동 (TMO : Time-triggered Message-triggered Object Model)에 대한 구조를 일반적인 형태의 구조로 모델링 하였으며, 이러한 모델링은 분산된 실시간 통신 객체와 비실시간 객체를 포함하여야 하고, 메시지 구동과 시간 구동을 모든 객체 구조 형태에 적용함으로서 실시간 통신 프로그래밍 설계가 이루어질 수 있다. 본 논문에서는 이러한 TMO 구조를 이용하여 실시간 통신 시뮬레이션 프로그래밍을 하기 위해 환자 모니터 원격진료 시스템 응용 환경에 적용하였다. Central Monitor로부터 전송되어진 환자의 생체정보 Raw Data가 HIS의 데이터 수신 모듈을 통해 사용가능한 데이터로 재구성될 수 있도록 설계가 이루어져 있다.

  • 본 논문에서는 TMO 실시간 객체 모델을 이용하여 실시간 통신 메시지 서비스를 효과적으로 지원하기 위해 새로운 프레임워크 및 동기화 메카니즘을 나타내었다. 또한 분산된 네트워크 시스템에서 TMO 구조를 이용하여 DHS(Distributed High-Precision Simulation) 응용 환경 에 적용함으로서 실시간 메시지 서 비스를 보장하였다. 분산된 다중 노드 시스템에서 TMO의 시간 구동 및 메시지 구동 구조는 실시간 통신 서비스 능력을 적시에 보장하기 위한 설계자의 노력을 충분히 줄일 수 있었으며, 제안된 프레임워크는 분산된 객체 구성요소들 사이의 데드라인 시간을 보다 쉽게 보장하기 위해 일관된 구조 및 구성을 제공하였다. 프로그래머의 데드라인 설계 시간을 처음 객체부터 적용하여 보장함으로서 형성될 수 있다. TMO 객체 모델을 기반으로 한 실시간 시뮬레이션에서 몇 가지의 TMO 구조의 장점을 가지고 있으며, TMO 객체 모델은 요구 명세서와 설계 사이의 강력한 연관성을 가지고 있다.

  • 실시간 처리의 가장 큰 목적은 시스템에서 동작 하는 실시간 태스크들이 주어진 데드라인을 잘 지키도록 하는 것이다. 본 논문에서는 임베디드 시스템을 위한 운영체제인 TMO-eCos의 실시간 태스크 스케줄링 성능 개선을 위하여, TMO(Time-triggered Message-triggered Object) 모델에 필수 요소로 규정된 BCC(Basic Concurrency Control) 스케줄러의 구현과, 실시간 객체 TMO의 객체 기반 프로그래밍을 제공하는 TMO 지원 라이브러리의 설계 및 구현에 관하여 기술한다. BCC 스케줄러는 보장성 컴퓨팅 설계를 위한 것으로, 비동기적 사건 구동 태스크의 스케줄을 사전에 스케줄이 정의된 시간 구동 태스크의 구동 시간을 제외한 여유 시간이 충분할 때에만 허용하는 실시간 스케줄러이다.
