Description
technical field [0001] The invention belongs to the field of airborne cockpit display systems, in particular to an airborne display graphics generating device and a method thereof. Background technique [0002] With the continuous improvement of aircraft's requirements for human-computer interaction, separate small displays can no longer display a large amount of complex information, and the research on airborne large-screen display technology has gradually become the mainstream. The graphic generation device of the airborne cockpit display is gradually shifting from the generation technology based on the DSP (Digital Signal Processing, digital signal processor) + FPGA (Field Programmable Gate Array, Field Programmable Gate Array) architecture to the GPU (Graphic Processing Unit, graphics processing unit) unit) as the core graphics generation technology direction change. As the resolution of large-screen displays becomes higher and higher, the graphics generation system bas...
