摘　　要：Ｕｎｉｘ操作系统的实时化改造涉及调度、核心剥夺、存储管理、文件系统等各个方面。本文讨论在ＵｎｉｘＳＶＲ３．２上如何设计和实现实时文件系统；支持磁盘块连续的文件访问，减少在读写文件时引入的不确定时间延迟。Many aspects such as CPU scheduling, preemptive kernel, memory management and file system are involved in remaking Unix for real-time. This paper discusses how to design and implement real - time file system on Unix SVR 3.2, support the access of files consisting of contiguous disk blocks, reduce the nondeterministic time delay introduced by reading and writing files.
