| Abstract: | Aiming at the problem in usage of embedded operating system,management and use of memory are influencing the performance of embedded system seriously Four software optimization methods of memory management are put forward： the default memory access method;forced use of FCSE（Fast Context Switch Extension） method;lock cache method and strictly abide by the underlying Linux management method.Simulation results show that the software design method of this paper can optimize the ARM920T and embedded Linux memory management,improve the operational efficiency and the speed of processes and reduce system overhead. |
