Description

technical field

[0001] The invention relates to the field of radar data transmission, in particular to a high-performance data exchange system and method based on the AXI4 Stream interface protocol, which is used in a radar signal processor. Background technique

[0002] The radar signal processor has been developed for a long time, and its various aspects of technology are relatively mature. With the improvement of the performance of various signal processing devices, complex high-speed real-time radar signal processing systems have been realized, and the corresponding data interaction requirements between boards and chassis are getting higher and higher. key to digital signal processing systems. In today's high-speed real-time signal processing system. The data objects involved tend to be diversified. These different types of data often require data exchange and transmission between different functional modules or boards in the radar signal processing system, and these d...
