The invention provides a radar image display acceleration system based on the ZYNQ, and relates to the technical field of signal processing. The system comprises a DSP chip, a ZYNQ chip, a DDR3 chip and a display module; the DSP chip is used for extracting radar image information from radar echoes, the ZYNQ chip includes a first module, a second module and a processor PS, the first module is used for converting the DSP chip time sequence into the DDR3 time sequence, the second module is used for converting the DDR3 time sequence into the VGA time sequence, and the processor is used for controlling the first module and the second module for time sequence conversion, the DDR3 chip is used for storing radar image information data obtained after conversion through the first module, and the display module is used for displaying a radar image obtained after conversion through the second module. The system uses DDR3 to replace a dual port RAM to serve as a cache, a piece of DSP is omitted, the difficulty of design can be significantly reduced, the cost is saved, this system can be used for radar image display, the resolution ratio can be 1080P, the frame rate can be 40 frames, and the requirement of mage display in most occasions can be met.
