Second , research the memory management mechanism of java virtual machine such as garbage collecting technique and discuss the issues of memory leakage and performance 其次研究了java虚拟机的内存管理机制,如垃圾回收技术,并对其内存泄漏以及性能等问题作了探讨。
Through the study on linux , we chose the embedded operating system uclinux as software platform of the system , much work is focused on uclinux ' s process and memory management mechanism determines the performance of the system 通过对linux操作系统的分析与研究,选择嵌入式操作系统uclinux作为系统的软件平台,着重分析了与服务器性能息息相关的进程和内存管理机制。
The research on linux 2 . 4 has been done , the emphasis of the study is put on process manipulated and process scheduled , interrupt response and interrupt handling , file system , inter - process communication , the memory management of the popular uclinux embedded operating system , and programming linux device driver 研究了版本为2 . 4的linux内核,重点是内核的进程管理和调度机制,中断响应和处理机制,文件系统机制,进程间通信机制,研究了比较流行的嵌入式操作系统uclinux的内存管理机制。
To improve virtual memory management mechanism , the kernel code is amended to avoid the incertitude cause by page scheduling , thus the responding speed is effectively improved . the irrationality of linux scheduling mechanism is also analyzed , and the methods and models such as to fortify scheduling occasion and adopt double kernel are also proposed to improve it 在虚拟内存管理机制的改进上,作者从操作系统内核入手,对内核代码进行修改,去除了由于页面调度带来的响应不确定性,有效的提高了系统的响应速度;在实时调度上,分析了linux现有调度机制的不合理性,提出了增加调度时机、采用双内核等方法,给出了改进的模型。
