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...
