Abstract

In order to satisfy the demand for integrated video and graphics processing technique in a cockpit display system

a method about airborne video graphics fusion display and video recording system based on SoC is proposed in this paper. Hardware platform is designed based on SoC. The graphics generation algorithms and video acquisition are performed by ARM processor and video graphics assist processor integrated in SoC. A double buffer and multi thread concurrent mechanism is designed to realize video graphics fusion display and real-time recording of video in cooperation with high speed storage and display interface integrated in SoC. Multiple formats resolution video source acquisition and large resolution graphics generation are supported by the proposed method. Experiments show that when capturing with 1024768 resolution video and generating with 19201080 resolution graphics

the fame rate is 45 fps

which satisfies the requirements of the cockpit display system.
