The invention discloses an implementation method for automatic circulating memory of an NANDFLASH memorizer. The implementation method comprises an electrifying record process of a memory system and a data playback read process of the memory system, wherein the NANDFLASH memorizer serves as a mass memory carrier; an FPGA serves as a control and data processing system, and is used for realizing circulating writing, circulating reading, circulating erasing and bad block checking of data; the USB 2.0 serial port technology is adopted for realizing high-speed playback of large volume data; a host computer can read data in a visualized sectional manner during data matching with a real-time clock. The implementation method has the advantages that defects of slow reading, manual erasing, failure in circulating memorizing, and un-intelligent read manner of large volume data are overcome; requirements of memorizing and managing of large volume high-speed data of an aviation digital acquisition system in the future are met.
Description
technical field [0001] The invention relates to a large-capacity storage control technology, which is suitable for a bomb-loaded large-capacity storage system with automatic data circulation storage, and in particular relates to a method for realizing automatic circulation storage of a NAND FLASH memory. Background technique [0002] With the development of aviation technology, there is an urgent need for a data acquisition and recording system with a variety of input signal types, multi-channels, and high sampling rates, regardless of missile-borne, space-borne or ship-borne measurement requirements, an urgent need for a large storage capacity, Intelligent data storage and erasing, fast and convenient data reading. However, the data recording system currently used in missiles usually cannot automatically cycle and store, and cannot read selected data segments. Contents of the invention [0003] The present invention provides a new type of large-capacity data storage cont...
