基于arm的视频处理系统设计_硬件与视频采集 摘 要 开发平台是GEC6818开发板，核心板使用了多层板相接的设计，能保证运行代码功能时稳定可靠。可以大量用于开发现代科技科技产品，例如高端平板电脑、POS机、互动平台机、智能监控设备等多种领域。开发板上搭载了八核处理器S5P6818，兼备着三星Cortex-A53系列高性能芯片的功能。使用时最高主频能够达到1.4GHz，可满足开发人员应用于嵌入式Linux操作系统的应用开发以及驱动开发。 嵌入式系统是人们自由控制、实现某些功能的要求，集成相对应的os和功能软件计算机里面，让项目软件与硬件一体化。。现在已经被应用于多个场景，包括控制工业、农业融合过程、通讯设备、测试仪器、无人驾驶汽车、船、飞机、火箭、军事装备、消费类产品等多个场景。市面上有很多已经做好的摄像头和录制声音的仪器，它们并不能灵活地用到人们想用到的场景，不能完全做到自定义的监控、录制视频音频的情节。嵌入式的视频音频采集系统可用于国防、医疗器件、家庭安全等等的场景，自由度极高，可以方便个人自定义录制视频音频的情况。多媒体通信技术的快速发展为信息大爆炸的21世纪提供了丰富的信息传输方式，视频传输、音频采集及其传输系统是其中不可或缺的重要组成部分。 关键词：GEC6818开发平台，软件与硬件一体化，视频、音频采集 Design of Video Processing System Based on arm Hardware and Video Acquisition Abstract The development platform is the GEC 6818 development board. The core board uses a multi-layer panel connection design to ensure that the code function is stable and reliable. It can be used to develop modern technology products, such as high-end tablets, POS machines, interactive platform machines, smart monitoring devices and other fields. The development board is equipped with an eight-core processor S5P6818, which also features Samsung Cortex-A53 series high-performance chips. The maximum frequency used can reach 1.4 GHz, which can be used by developers for application development and drive development of embedded Linux operating systems.Embedded systems are the requirements for people to freely control and implement certain functions. They integrate the corresponding OS and functional software computers to integrate project software and hardware. And ... It has now been used in multiple scenarios, including control of industry, agricultural fusion processes, communications equipment, test instruments, unmanned vehicles, ships, aircraft, rockets, military equipment, consumer products and many other scenarios. There are many cameras and recording instruments that have been made on the market. They do not flexibly use the scenes that people want to use. They can not fully implement custom monitoring and recording video
