碩士 === 國立成功大學 === 航空太空工程學系 === 82 === An operating system of computer is responsible for managing all system resources and activities among resources. Ordinary operating system has following shortcoming : 1. CPU is not utilized efficiently. 2. System lacks capability to deal with emergent events. 3. It lacks capability of multitasking. 4.It is difficult to integrate system resources. Some environment requires strict operating capability , so the system built on the operating platform can not satisfy all actual demands. For the sake of resolving these problems, a systemis provided with following characteristics at least:1.System can manage various events depending on their emergent levels. 2.System is equipped with capability of multitasking to handle a lot of events simu- ltaneously. 3. System can integrate all resources according en- vironment's different demands. 4. System can complete datum ex- change fast and right. A real-time multitasking system can sat- isfy our requirements. Not only the response time of the system has specific time limitation, but also it has explicit results of managing events and can handle a lot of events simultaneously . Thus we use real-time multitasking system will be able to re- solve the above-mentioned problems and improve system performance . In this dissertation, we will introduce basic framework of real -time multitasking system and how to design real-time multitas- ing system. Finally we will design a DC motor real-time control system and propose future advanced research.
