Description

Technical field: [0001] The invention relates to a high-speed data recording system based on an FPGA+DSP framework and a construction method thereof, and the design belongs to the technical field of communication. Background technique: [0002] In the development of modern communication, all kinds of data communication have occupied an important position. In more and more cases, the storage and analysis of real-time data has become a widespread demand of users. In various scientific research and testing, data storage and analysis has become an important and necessary means. Data storage devices (commonly known as black boxes) have been widely used in real life. If it is applied to an aircraft, recording various flight parameters recorded by the black box is an important basis for finding and analyzing the cause of an aircraft accident. In addition, vehicle-mounted and ship-borne black boxes are gradually being used. But even in the civilian field, data recording equipmen...
