Abstract

A real-time operating system (RTOS) supports applications that must meet deadlines in addition to providing logically correct results. This paper reviews pre-requisites for a real-time scheduler in RTOS to be POSIX 1003.1b compliant and scheduling in RTOS. A comparison of the schedulers is presented. We survey the prominent research oriented schedulers and outline steps in system implementation of parametric scheduler for RTOS.

Workstations and personal computers are increasingly being used for applications with real-time characteristics such as speech understanding and synthesis, media computations and I/O, and animation, often concurrently executed with traditional non-real-time workloads. This paper also presents a system that can schedule multiple independent activities. Activities can obtain minimum guaranteed execution rates with application-specified reservation granularities via CPU Reservations. We conclude by discussing the results of the survey and suggest future research directions in the field of scheduler for RTOS.
