File-type high-speed data stream access device and method thereof

Abstract

The invention discloses a file-type high-speed data flow access device which comprises a data acquisition interface, a buffer, a flash control interface, an IDE interface, a flash memory, a data block counter and a nonvolatile memory, wherein, an input terminal of the data acquisition interface is connected with high-speed data flow, and an output terminal of the data acquisition interface is connected with the buffer; the flash control interface stores data in the buffer to the flash memory; the data block counter stores the number of data blocks in the nonvolatile memory; and the IDE interface reads out the data in the flash memory to a main memory in a file block format. The invention realizes real-time storage and high-speed file processing of the high-speed information data flow, and people only need to access or unload the high-speed data flow by a file read-write mode without additional preprocessing when in application, thus saving time, improving efficiency, strengthening performances of an embedded computer system, and having the characteristics of fast speed, good stability and the like. The invention further discloses a file-type high-speed data flow access method.

Description

technical field [0001] The invention relates to storage and transmission of streaming files, in particular to a high-speed data streaming file access device and method. Background technique [0002] With the rapid development of information technology and its increasingly extensive application, people have put forward higher requirements for large-capacity information storage, automatic processing and rapid transmission. However, when the existing technology stores high-speed information, it cannot be documented. Therefore, when applying it, people have to face a large amount of complex data, with a large amount of processing and low efficiency. If the data is forcibly documented, Then the real-time storage of high-speed data cannot be realized, that is, the requirements of both documentation and real-time performance cannot be taken into account when storing high-speed data. To solve the real-time storage and simplification of manual processing of the above-mentioned high-...

However, when the existing technology stores high-speed information, it cannot be documented. Therefore, when applying it, people have to face a large amount of complex data, with a large amount of processing and low efficiency. If the data is forcibly documented, It is impossible to realize real-time storage of high-speed data, that is, when storing high-speed data, the requirements of both documentation and real-time performance cannot be taken into account.
