A Kind Of SSD File System With SRIO Interface

With the continuous development of embedded technology, embedded platform is more and more high to the requirement of high speed large amount of data storage.In the field of embedded, Serial RapidIO is a kind of high performance interconnection technology based on packet switching, with low latency and high bandwidth and the advantages of high reliability, Internet provides a good solution for the inside of a system.Linux system as open source operating system, and satisfy the embedded system to the needs of high reliability, high safety and high stability.In order to realize high speed large amount of data storage, USES the Linux file system and based on Serial RapidIO interconnected system is to build the combination of high speed large capacity embedded storage file system feasible way.Mainly on the client server mode of file access, process of data exchange and data exchange protocol are analyzed and the research such as technology, realized based on the corruption under the Linux file system of the large capacity storage,Serial RapidIO direct IO/DMA mode fast data transmission and a file system of the large capacity of the embedded platformThe main work is as follows:(1)Realize remote access to the file of the user the design process, through the Ethernet transmission control flow, Serial RapidIO transport data stream, and QorIQ P4080 as server handle user request, large capacity, high rate of storage module, so as to make the work rate of 732 MB/s.(2) optimize the file system, makes file read with SRIO to send a level 2 lines, in parallel to read and send the data.(3) set up the experimental platform, in the condition of the whole system through a user programming apis for file system access rate was tested, the results showed that access rate to a maximum of 1 GB/s.The experimental results show that, the file system in terms of functionality,reliability, and performance meet the design requirements, realized the function of high speed large capacity storage, within the platform connecting users can remote access to the file system.By designing a SRIO interface of solid file system, to a certain extent, solve the problem of high speed large capacity storage embedded platform, the main innovation point is by implementing a secondary line, improve the literacy rate of file system.
