Design of eMMC Radar Data Storage System Based on ZYNQ
In order to meet the requirements of airborne radar data storage system for large data capacity and fast reading and writing speed,a design scheme of eMMC radar data storage system based on ZYNQ was proposed.The system uses ZYNQ-7000 series chip as the main control chip,analyzes and frames the received radar data and GPS data through the PL terminal,and transmits the framed data to the DDR cache of the PS terminal after combining the ping-pong cache technology with the AXI4 bus,and then writes it into the eMMC memory unit,and reads back the verification data after storing it.Experimental results show that the data storage speed can reach 60 MB/s,the system runs stably and the stored data is complete.Compared with other radar data storage systems,this system has the advantages of high capacity,high integration and fast storage speed.
