Managing Dynamic Memory in Embedded Software Systems

摘要

Dynamic memory management allows memory to serve different purposes at different times. As embedded software systems increase in complexity and size, it is increasingly important for such systems to support dynamic allocation and deallocation of memory. This dynamic use of memory enables expanded capabilities and features and introduces greater flexibility in embedded products. Developers who use dynamic memory management in embedded systems need to pay special attention to performance, security, reliability, and predictability considerations associated with the implementation of their dynamic memory management subsystems. This class reviews these issues, and compares various popular techniques for explicit dynamic memory management in C and C++, as well as automatic dynamic memory management in Java. Advanced dynamic memory-management techniques, including real-time garbage collection and generational garbage collection, are also discussed.
