μC/OS与FREERTOS动态内存管理机制的分析与比较

摘要

In the embedded system ifeld,every programmer has to face the problem about how to reasonably allocate and manage the RAM resource.Stability and reliability of a whole system are determined by the programmer's capability to carry out efifcient,reliable and real-time management of dynamic memory partition.Based on in-depth study of μC/OS and FREERTOS dynamic memory management mechanism,the paper comparatively analyzes the advantages,disadvantages and the application occasions,which facilitates developers to make targeted selection of operating systems based on different product requirements in practical applications.%在嵌入式系统领域，如何合理地分配和管理系统内存RAM资源是程序员必须面对的问题，能否高效、可靠、实时地管理动态内存分区决定了整个系统的稳定性和可靠性。本文以μC/OS与FREERTOS两种操作系统为例，在深入研究其动态内存管理机制的基础上，对其优缺点和适用场合进行了分析比较，便于软件开发人员在实际应用中根据产品不同需求进行针对性的选择。
