Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as figure 2 As shown, the interface module between the graphics generation and display system and the host computer includes a decoder and a data buffer, wherein the decoder is implemented by a single-chip CPLD chip, and is responsible for receiving drawing instruction data from the bus, decoding and transferring the received instruction data to Stored in the data buffer; the data buffer adopts dual-port RAM (64K words). In order to ensure the continuity and integrity of instruction data transmission, the dual-port RAM is divided into two data buffer areas (namely, A area and B area). These two buffer areas receive and output data in a cycle-alternating working mode: in a certain cycle, area A caches all graphics instructions from a frame of graphics transmitted by the host computer, and area B is under the control of the graphics engine at this ...

Abstract

The invention discloses a graphical display system based on an airborne graphic engine. The system comprises a bus interface, the graphic engine, a frame storage, a power module, a configuration module, a graphic engine and a video strobe / conversion module. The specific airborne graphic engine design method and the graphical display system framework are provided, and the graphic engine is the core of a whole graphic system, and is responsible for being in bus communication with an upper computer, high-speed generation of graphic images, buffer memory of video images, input / output control over the video and the like. The graphical display system can achieve real-time display of the large-screen and high-resolution airborne graphic images, and mixed display of the airborne graphic images and the externally-input video graphic images is achieved. Compared with the prior art, the system has the advantages of being high in graphic generation and processing speed, high in display resolution, high in function comprehensive degree, high in system integration, small in size, low in power consumption and the like.

Description

technical field [0001] The invention relates to the field of graphics generation systems, in particular to a graphics display system based on an airborne graphics engine. Background technique [0002] Today, with the rapid development of the information society, the airborne cockpit graphic display system has been widely used in the aircraft cockpit display. The cockpit display is one of the most important human-machine interfaces between the pilot and the aircraft system and the surrounding environment. The use of large-screen displays to replace the multiple multi-function displays currently used can reduce the time spent by pilots on information management and integration, and by increasing the effective display area on the cockpit instrument panel, more flight information can be presented, which can effectively enhance the pilot's Knowledge of the "situation" in flight. [0003] The current airborne display system mainly adopts the hardware architecture based on DSP+FPG...
