Aerial pattern processing system based on ARM

Abstract

The invention belongs to a computer figure display technology, and relates to an aerial figure processing system based on ARM. The aerial pattern processing system comprises a hardware part and a software part, wherein the hardware part is composed of a micro-processing circuit, a communication circuit, a button acquisition circuit and an AD conversion circuit; the software part comprises a software environment and a software logic structure. On the basis of achieving existing functions, the function and performance of a display type product are improved; meanwhile, the quantity of chips is greatly reduced, the occupied area is reduced, the development difficulty is lowered, and the project development cycle is shortened.

Description

technical field [0001] The invention belongs to computer graphics display technology, and relates to an ARM-based aviation graphics processing system. Background technique [0002] Aviation graphics processing system is mainly used in aviation display or display control computer, mainly realizes the generation and display of airborne images, and comprehensively displays for pilots: attitude, speed, altitude, heading and other main flight information; navigation map (superimposed route information on digital map) , aircraft estimated position and navigation parameters, etc.); landing / landing guidance information; meteorological information; ground proximity warning graphics; engine parameter information; [0003] At present, the airborne display system is mainly divided into two types. The simple function only supports simple graphics acceleration functions, such as filling, drawing dots and dashes, copying, etc., and does not support OpenGL. The other is to use the GPU on t...
