Airborne display graphic generation device and generation method

Abstract

The invention discloses a display graphic generation device which comprises a graphic SOC (Stress Optical Coefficient) processor, an instruction data processing unit integrated inside the graphic SOC processor, a graphic generation unit, a graphic processing display control unit, a video processing display unit, an internal memory unit, a program memory, a first frame memory, a second frame memory, a third frame memory, a first video decoder chip, a second video decoder chip and a third video decoder chip. The invention further provides a double-screen splicing graphic synchronous generation method based on a virtual frame memory, and through the double-screen splicing graphic synchronous generation method, the non-standard high-resolution graphic synchronous generation and the double-screen synchronous generation are supported, and the flexible switching of single-screen display and double-screen display pictures and the multi-graphic resolution ratio display are supported. Compared with the prior art, the display graphic generation device has the characteristics of high graphic generation and processing speed, high display resolution ratio, high function integrated degree, high system integration degree, small size, low power consumption and the like, and a solution with low power consumption and high performance is provided for large screen display graphic character generation and processing.

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 has gradually shifted from the generation technology based on DSP (Digital Signal Processing) + FPGA (Field Programmable Gate Array) architecture to GPU (Graphic Processing Unit, Graphics Processing Unit). graphics processing unit) as the core graphics generation technology direction change. As the resolution of large-screen displays becomes higher and higher, the graphics generation system based on the CPU+GPU architecture consumes more...
