Problems solved by technology

[0003] However, in the prior art, due to problems in the production process, there may be some bad blocks in the Flash memory when it leaves the factory.
These inherently bad blocks cannot be used to store data
In addition, due to the increase in the number of reads and writes during use, good blocks will become unstable or invalid, and become bad blocks (that is, use bad blocks)

Embodiment Construction

[0016] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0017] see figure 1 , the embodiment of the present invention provides a Flash storage file system, including a plurality of Flash chip arrays, and also includes: a storage block management module, wherein:

[0018] The storage block management module is used to organize the space blocks in the Flash chip array, according to the attribute information of the file, and use the space blocks of the required size to organize and maximize the parallel used Flash chips.

[0019] It should be noted that the storage block management module will utilize space blocks of the required size to organize in a specific way, and maximize the parallel use of Flash hardware for high-speed storage.

[0020] The following is a detailed introduction to the attribute information of the file and how the above-mentioned storage block manag...

Abstract

The invention discloses a Flash file storing system. The system comprises a Flash file storing block managing module, a file information managing module, a file operating and managing module and a specific operating and managing module for a signal system. According to the Flash file storing system, the actual storing space is managed by effectively arranging block addresses of a Flash chip array, the block addresses of the file system meet the using requirement of the high-speed Flash file storing system, a set of flexible file managing APIs are provided, and meanwhile a specific operation interface is provided for a signal recording system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a Flash storage file system. Background technique [0002] High-speed data acquisition is currently widely used in fields such as radar, signal processing, and communication that require signal recording. As a result, the demand for high-speed and large-capacity storage is getting higher and higher, and more requirements are put forward for the flexibility and stability of the storage system. high demands. Therefore, the development and research of the file system for high-speed Flash storage has great practical significance. [0003] However, in the prior art, due to problems in the production process, there may be certain bad blocks in the Flash memory when it leaves the factory. These inherently bad blocks cannot be used to store data. In addition, due to the increase in the number of reads and writes during use, good blocks will become unstable or invalid, and become bad...
