摘要
基于ARM核微处理器S3C44BOX为核心的视频信号模拟器,是将高性能、低功耗的微处理器S3C44BOX与嵌入式实时操作系统μCos-Ⅱ相接合,利用C语言的优势,添加人机交互方式、图形化界面;使系统具有回波图像逼真、可方便地实现多目标模拟、系统扩展性好等优点。本文简要介绍了基于微处理器S3C44BOX芯片的开发平台,并给出了基于S3C44BOX开发平台视频信号模拟器的硬件组成及详细的软件流程图,并给出实验结果。
The video signal simulator is based on the chip of S3C44BOX. MPU S3C44BOX,which has high performance and low consumed power, works with an embedded real-time operating system μCos-II. It combines the man-machine interaction mode and graphical interface, and programs in C language.This system has many advantages, such as lifelike echo image,expediently realize many objects simulation, extend performance all right. This paper briefly discusses the characters of the MPU S3C44BOX. The video signal simulator is based on the chip of S3C44BOX hardware diagram and the program and flow chart of ARM have been given.
