Design and Implementation of Real-Time Executive (RTDM) for Multitask System


Abstract:The purpose of this paper is to design an efficient, reliable, fast, easy to extend, andsmall size experimental real-time operating system kernel for uniprocessor multitasksystem. It is a kernel with an underlying formal model based on periodic and sporadic taskswith guaranteed response time requirements to tasks and shared software resources. It isdistinguished by the programming model it supports and its use of a new processorscheduling and resource allocation.The kernel represents a nucleus of supervisory softwareto perform the required real–time functions. It logically runs and coordinates concurrentand physically asynchronous activities. It offers appropriate synchronization and taskcommunication mechanism among tasks.
