USING ASPECT-ORIENTED SOFTWARE DEVELOPMENT IN REAL-TIME EMBEDDED SYSTEMS SOFTWARE - A Review of Scheduling, Resource Allocation and Synchronization

Abstract

Timeliness and criticality of a process are the two main concerns when designing real-time systems. In addition to that embedded systems are bounded by limited resources. To achieve these concerns while at the same time using a minimal amount or resources, real-time embedded systems use different techniques such as task scheduling, resource management and task synchronization. These techniques involve a number of the modules of the system which makes the use of Aspect-Oriented Software Development imperative. AOSD is a programming technique which uses the notion of join points to capture specific locations in code execution and then use advices to insert new code. This paper examines existing work in the development of schedulers, resource allocation agents and synchronization techniques using Aspect-Oriented Software Development in real-time embedded systems. An analysis of the existing research is used to describe the advantages of using AOSD over conventional OOP methods and to identify areas where further research may be required.
