| Summary: | 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.
