在UNIX中实现实时进程的存储管理

IMPLEMENTATION OF MEMORY MANAGEMENT OF REAL-TIME PROCESS IN UNIX

为提高UNIX实时性,本文论述对Unix System V Release 3.2(简称UnixSVR 3.2)的存储管理的改造技术,使其支持实时进程的存储管理,实现实时进程的可执行文件预装入、页面在内存锁定,以及当实时进程过多时有条件的实时进程对换。

This paper discusses the remaking of the memory management in Unix SVR 3. 2 for supporting real - time process. The combining strategy has been implemented: preloading executable files, locking pages of real - time process in memory, and conditional swapping real - time process when the total space of real - time processes exceeds the amount of memory.
