适合于大规模数据快速存取的文件系统设计

A Design of File System Suited Large-scale Data and Quick Access

由于现在微机上广泛使用的通用操作系统对文件的管理采用的是事务性管理方式,另外由于兼容性的要求磁盘空间的直接管理能力不能超过32M从而限制了它在许多场合中的应用.本文以我们新近研制适合于大规模数据快速采集处理的实时多任务操作系统FRTOS 88为例,全面完整地描述适合于大规模数据快速存取的文件管理系统设计方法和关键结构算法。描述的重点放在本文所提出的支持多级子目录结构的连续文件管理策略上。

Because general purpose operating systems widely used in the microcomputers adopt the metheod oriented general affairs to supervise files, in addition, the direct management ability of disk is less than 32M, these all limit their application in many aspects. Taking a new real-time and multitask operating system FRTOS 88 as instance, which has been developed by us recently to aim at the environment of large-scale and quick data acguisition and processing, this paper will all-sidely describe the file management system design, key structures and algorithms suited for large-scale data and quick access. The disscussions will centre on the organization strategy of multilevel subdirectory and sequential file system.
