A new remory management mechanism based on embedded system

摘要

This paper expounds a predictable and adaptive management of the embedded system dynamic memory. The solution puts the survivable design in a memory static area and partitions in dynamic area again. It puts those similar objects in the object pool subarea, and the other applicants are distributed in normal subarea. Both subareas adjust the size by transmitting parameters. In normal subarea, the paper puts forward predictable mechanism for the first time. Besides, by introducing a new data structure and combining classic buddy algorithm, it improves the adaptive algorithm of delay recovery with statistical data and applicant time interval. Finally the solution is confirmed more safely and efficiently by simulation experiments.
