基于SoC的机载显示器视频图形融合处理系统
Video and graphics fusion system based on SoC in cockpit display system
摘要
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 sys-tem based on SoC is proposed in this paper.Hardware platform is designed based on SoC.The graph-ics 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 1 024×768 resolution video and generating with 1 920×1 080 resolution graphics,the fame rate is 45 fps,which satisfies the requirements of the cockpit display system.关键词
