Embodiment Construction

[0027] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0028] see figure 1 , the present invention provides a flash-based streaming file system, which is characterized in that the flash is divided into a plurality of storage units, and the storage units include system clusters and data clusters; system clusters are used to store logs, backups, file directory tables, file Allocation Table;

[0029] The invention provides an independent file operation interface, uses relatively small memory, and therefore does not need strong operating system support.

[0030] The so-called file directory table is FDT (File Directory Table), and the file allocation table is FAT (File Allocation Table). Data clusters are used to store data. The so-called cluster is the smallest unit of flash space that can be ...

Abstract

The invention provides a stream-oriented file system based on flash and a method for reading and writing files. The stream-oriented file system based on flash comprises that the flash is divided into a plurality of storage units. The storage unit is divided into a system cluster and a data cluster. The system cluster is used for storing logs, backups, file catalogue lists and file distribution tables. The data cluster is used for storing data. Therefore, reading and writing of the files can be conducted by first looking through cluster head information of each cluster and then obtaining types and space using conditions of each cluster. Cost time is less due to the fact that only information of cluster head portion is read. Information such as beginning cluster, size, modifying time and storage distribution condition of the files can be obtained by reading the system cluster, so that matched clusters can be found more effectively, and then reading and writing can be conducted on the files. Simultaneously, free clusters can be effectively distributed due to the fact that space using condition of each cluster can be obtained, and management of the storage space is more effective.

Description

technical field [0001] The invention relates to the field of a streaming file system, in particular to a flash-based streaming file system and a method for reading or writing files based on the system. Background technique [0002] As various cards are used in consumer transactions, POS is also widely used in various merchants. Generally speaking, POS machines need to store various transaction data, such as transaction merchant, location, time, transaction type, card number and other information. The original POS only needs to provide a record file system to record these flow data to meet the demand. However, with the diversification of POS application forms, POS machines not only need to store transaction flow data, but also store other forms of data, such as user-personalized interface data, fonts, graphics, or various script data. As a result, the original record-based file system cannot meet the growing needs of users. Therefore, a simple, easy-to-use, portable, and lo...
