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. Start after striking space key 2 times.

According to the necessity of measuring equipments for advanced military systems, real-time characteristics such as time determinism and execution accuracy pursuing low-latencies have become very important. With this reason, the market demand for real-time features in the general purpose operating system such as Linux has been enlarging. To meet these requirements, RTLinux and RTAI has been developed as dual-kernels based on Linux. However, developers should use assembler languages to facilitate real-time in RT-Linux, it is very difficult to deal with it. RTAI has disadvantage that it only provides soft real-time. To solve these problems, RTiK-Linux was developed. In this paper, we propose a new dual-kernel with hard real-time capabilities in Linux, called RTiK-Linux(Real-Time implemented Kernel for Linux). We first introduce related researches and then describe the design methodologies to guarantee the resolution which almost accords with the timer settings. Finally, we present the results of experimental measurements and analyze them in order to validate and evaluate the proposed RTiK-Linux.

최근 SoC를 포함하는 대부분의 임베디드시스템에서는 RTOS가 선택이 아닌 필수적인 구성요소가 됨에 따라 SoC 개발의 초기단계에서부터 RTOS를 도입하는 것이 바람직하다. 하지만, 기존의 범용 RTOS가 제공하는 기능은 대부분 응용 소프트웨어의 개발과 수행을 위한 것으로 SoC 개발 및 검증에는 적합하지 않은 문제점을 가지고 있다. 본 연구에서는 SoC 개발을 위해 운영체제가 만족시켜야할 요구사항을 제시하고, 소프트웨어의 재사용성과 SoC의 검증을 함께 지원하는 VPOS(Verification-Purpose OS)를 개발하였다. VPOS는 초경량의 단순한 계층적 구조(layered structure)를 가지는 RTOS로서 소프트웨어 재사용을 위해 POSIX 표준 API, 유닉스 호환 디바이스 드라이버 인터페이스, HAL 등을 제공한다. 또한 SoC 설계의 검증을 위해 RT 수준의 통합시뮬레이션에 적합한 커널 구조 및 최적화된 코드, 하드웨어 테스트를 위한 쉘 명령어, 응용 소프트웨어의 디버깅을 위한 KREM(kernel resource and event monitoring) 등의 특징을 함께 제공한다.
