| Abstract: In the embedded system field,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 efficient,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. |
