证明了通过内核脚本执行引擎提升用户程序执行系统调用系统得可行性 关键词: 内核脚本执行引擎
脚本执行引擎编译用户进程提供的脚本文件
可以有效地减少用户进程频繁的执行系统调用中需要进行用户态和内核态的状态转换次数
然后介绍了位于Linux内核的脚本执行引擎的实现及其组成结构
减少了用户进程执行系统调用耗费的时间
完成用户进程对内核服务的访问请求
Linux系统调用
) 摘要: 本文先分析了Linux系统调用的过程
进而提升了用户进程执行的性能
) Abstract: This paper first analyzed the procedure of executing Linux system call, introduced the way of using kernel script engine to execute system call
It explained the way of implementing the kernel script engine, which used compiler technology to help user-space process to access the service provided by the kernel
In that way, normal user-space process could decrease the number of switching between kernel mode and user mode, getting the performance improved
The final test results indicated that the kernel script engine could enhance process\ns system call performance
workflow technology had been widely used in the office atomization system
This technology could greatly enhance the working efficiency
