The invention belongs to the technical field of image videos, and discloses a method and a system for realizing image video display based on an FPGA (Field Programmable Gate Array) carrying chip. The ARM processor receives a video display instruction periodically issued by an upper computer, generates an indication signal and a sub-block image data sequence number for the display control processor FPGA, triggers the display control processor FPGA to sample, stores the indication signal and the sub-block image data sequence number into the BRAM according to the sequence number, and replies a handshake signal to the ARM processor after storing pixel control information of a complete sub-block; and the ARM processor is triggered to send next sub-block image data until the display control processor FPGA receives and stores background area information of all videos, the image encoder state machine is triggered to work, and display control tasks of different scene pictures are completed through an encoder BT656 transmission protocol. According to the invention, the display control of the airborne equipment is suitable for more different scenes, the control is more flexible, and the hardware cost is lower.

    本发明属于图像视频技术领域,公开了一种基于FPGA搭载芯片实现图像视频的显示方法及系统。ARM处理器接收上位机周期下发的视频显示指令,对显控处理器FPGA产生指示信号和子块图像数据序号,触发显控处理器FPGA进行采样,并按序号存入BRAM,存储一个完整子块的像素控制信息后,回复所述ARM处理器一个握手信号,并触发ARM处理器发送下一个子块图像数据,直到所述显控处理器FPGA接收并存储完所有视频的背景区域信息,触发图像编码器状态机工作,并通过编码器BT656传输协议,完成不同场景画面的显示控制任务。本发明使得机载设备的显示控制适用于更多的不同场景,控制更加灵活,硬件成本更低。
