Survey Report on Memory Allocation Strategies for Real Time Operating System in Context with Embedded Devices

摘要

An embedded system is a computer system designed for specific control functions or for any dedicated application, often with real-time computing constraints. Real time operating system (RTOS) is specially used to meet the real time constraint and to support the sophisticated facilities provided by embedded system. While designing any embedded system memory management is an important issue. Embedded system developers commonly implement custom memory management facilities on top of what the underlying RTOS provides. That’s why understanding memory management is therefore an important aspect. In this paper we are dealing with different memory management strategies and algorithm that are used in real time operating system in order to improve the performance of the intended application. Firstly we have compared the static and dynamic memory management strategy and then we consider different algorithms that can be used to implement the dynamic memory management in real time operating system.
