Abstract

The invention discloses a storage control system. The system comprises an FPGA module used for data acquisition, instruction analysis and data storage; an ARM module used for carrying out file management on the NAND Flash data, collecting bad block information, carrying out instruction analysis, carrying out storage management operation and carrying out data management; a DDR module used for caching file system information data of high-speed data storage and data writing, reading and deleting operations; and a NAND Flash module used as a data storage carrier. By integrating the FPGA module, the ARM module, the DDR module and the NAND Flash module, online real-time high-speed transmission, processing, storage and data management of various data are realized. The ARM module design is added,the real-time performance of data and the performance of file management are enhanced, and a large-capacity, diversified and high-speed storage control system integrating data recording, storage, exporting, storage space management, file management, state query and UART serial port configuration is formed.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a storage control system. Background technique [0002] In the future spaceborne applications, the status of information will become increasingly important. The spaceborne real-time information processing system has the characteristics of large data and rich connotations. New challenges are raised, and it is necessary to realize online real-time storage, data transmission and data processing of large amounts of data. [0003] Our country has made certain achievements in the research of on-board solid-state memory, and has obtained a series of popularization and application in model missions, but there is still a gap between the overall level and the international level, which is mainly reflected in the modularization and integration of functional units of the on-board data processing system. Generalization, documented organization and management of scientific data, etc., ar...
