Embedded system is more and more popular in recent times, but the resources of embedded systems are few
relatively, the merit and shortcoming of memory management impact greatly on the overall performance of embedded
systems. On this account, this paper describes the memory management mechanism of embedded system, and researches
the unitary requirement and particular requirement of memory management module of embedded system. We put
forward some improved technology solutions of memory management aspect based on memory allocation mechanism,
which strengthens the real-time running of system, and reduces the response time.
