摘要
嵌入式系统功能的不断增加,将直接导致系统内存的不足.从用户层的角度出发,针对应用程序由于内存不足而造成系统的无法响应问题,对系统内存和单个进程内存使用情况进行分析,通过修改系统参数和对可执行文件elf的研究,提出了从系统和进程两方面对内存进行优化,以使更多的程序得到响应,提高系统的并发性.实验证明,这些方法的使用可以增加系统空闲内存5%左右,有效地提高了系统性能.
The continuous increase in functions of the embedded system directly results in memory shortage in the system.From the perspective of users,in order to solve the invalid response of the system because of insufficient memory of application programs,the memory usages of the system and single process are analyzed.By changing the system parameters and research on the executable file elf,a new method of memory optimization is put forward for both the system and processes,how more applications are able to be responded,thas improving its concurrency.Experiments show that the method can effectively increase the free memory of system and improve its performance.
