Embodiment Construction

[0045] see figure 1 , the present invention is realized based on a graphics card with a PMC structure. The graphics card consists of 1 graphics display chip, 2 video A / D conversion chips, 2 video driver chips, 1 FPGA chip and 2 SRAM (static random access memory). Such as figure 1 As shown, the graphics card receives two channels of external PAL-D video, which is connected to FPGA after A / D conversion. The graphics output by the graphics display chip are connected to the FPGA. After format conversion and superimposition of external video and graphics inside the FPGA, the video driver chip performs DVI (Digital Visual Interface) video output.

[0046] Video A / D conversion chip

[0047] After the graphics card receives two channels of analog PAL-D video signals, it completes functions such as analog-to-digital conversion, filtering, and standard code stream generation through the video A / D chip, and converts the analog video signals into digital video signals, and at the same...

Abstract

The invention relates to a graphic processing apparatus and a graphic processing method. The image processing apparatus comprises a graphic display chip, a video A / D conversion chip, a video driving chip, an FPGA chip and an SARM. The graphic processing method comprises the following steps of: firstly, sending an external video signal into the video A / D conversion chip to carry out analog-to-digital conversion and generate a standard code stream; secondly, carrying out video format conversion and video superposition; and finally, outputting a signal. Therefore, a comprehensive display picture not only has complicated graphical situation information, and also has rich external video information.

Description

technical field [0001] The invention relates to a graphics processing device and method. Background technique [0002] Current and future aircraft will face increasingly complex battlefield situations, and various battlefield information from sea, land, air, sky, and ground must be displayed to pilots in a timely and accurate manner. However, the traditional single display system based on characters and lines cannot display the information of the complex battlefield situation to the pilots in a timely and accurate manner. Information on the complex battlefield situation requires high-performance graphics processing technology in order to provide pilots with smooth, clear, vivid and accurate comprehensive display images. The comprehensive display screen not only has complex graphical situation information, but also has rich external video information. Therefore, there is an urgent need for a high-performance graphics processing technology. Contents of the invention [00...
