A multimodal storage system based on emmc array

Abstract

The invention discloses a multi-mode storage system based on an eMMC array, which relates to the technical field of storage systems, and includes an interface board, an interconnection backplane and a storage board, and the interface board includes a configurable interface module, which is used for different protocol types External data access; system main control module, used for storage system management; first cache module, used for seamless conversion of data streams between modules; Switch exchange module, used for interface main control chip and each storage main control chip The data distribution and transmission among them; the interface board is connected with each storage board through the interconnection backplane, and the storage board is used for modular expansion of the system. The present invention realizes hard destructive and highly reliable data storage through multi-level hardware redundancy and software automatic management, realizes dynamic compatibility with multi-protocol types through dynamic reloading of interface programs, and supports reading while recording through parallel read and write timing control and group flow operation And other multi-mode working modes, it is very suitable for applications such as airborne / missile-borne aerial measurement with harsh environments and high reliability requirements.

Description

technical field [0001] The present invention relates to the technical field of storage systems, in particular to a multi-mode storage system based on eMMC arrays. Background technique [0002] With the rapid development of the aerospace industry, a lot of testing work is required in the design process of missile and aircraft systems, especially the real-time recording of the working state parameters of each part in the system development and flight test is used to analyze and improve the design. The aircraft / missile data recording and storage system can collect, process and record various signals in real time during launch and flight, and read the test data stored in the recorder after the flight mission is completed to monitor the flight status of aircraft and missiles. for analysis. In recent years, with the gradual increase in the application of various high-resolution and high-frame-frequency photoelectric measurement equipment, the test data obtained through these dete...

Problems solved by technology

The advantage of this solution is that it has high storage density, and it can be miniaturized and lightweight while ensuring large capacity and high bandwidth; its disadvantage is that there is no fixed standard for NAND FLASH memory chips, bad block management in Technologies such as test and loss leveling need to be designed separately, the development cycle is long, and the update is fast, and it is not easy to maintain
