连续簇内存文件系统的设计与实现

Design and Implementation of the Continuous Cluster Memory File System

摘要: 在Windows环境下采用C++语言设计并实现了连续簇内存文件系统CCFS，采用链表结构管理连续簇，能够灵活适应内存空间高度可调的各类设备。针对单次写入数据量小导致降速的情况，设计了输入缓冲区，使得写入吞吐率提高30%以上，这对于进行高频少量数据读写的应用程序来说，加速效果十分明显。该文件系统在完整的存储空间内实现了数据存储和文件管理的所有功能，不仅可用于常规内存，还适用于非易失性内存，考虑磨损均衡后，还可用于写入次数有限的固态硬盘，具有广泛的适用性。

Abstract: The continuous cluster memory file system (CCFS) was designed and implemented using the C++ language in the Windows environment. It employs a linked list structure to manage continuous clusters, flexibly adapting to various devices with highly adjustable memory spaces. In response to the issue of reduced performance due to small data volume in a single write, an input buffer was also designed, resulting in a write throughput improvement of over 30%. The acceleration effect is very obvious for applications involving high-frequency and small-scale data read/write operations. This file system fulfills all data storage and file management functions within the full storage space, making it suitable not only for conventional memory but also for non-volatile memory. With wear leveling considerations, it can be applied to solid-state drives with limited write cycles, demonstrating broad applicability.
