摘要
嵌入式系统具有专用性强、系统精炼、高实时性以及系统内核小等优点。当前在图像处理领域，使用嵌入式系统处理实际问题已经成为了一个应用的热点。作为嵌入式系统的代表，以ARM9为代表的主流处理器得到越来越广泛的应用。基于上述背景，本文描述了以TI公司第一款DSP＋ARM架构的处理器TMS320DM6446作为开发环境，应用多线程技术，可实现”小型飞行器自主降落”的图像处理演示系统的设计和开发过程。
The embedded system is of the advantages of high-specificity, concise system, high instantaneity and small system kernel and so on. At present in image processing area,practical issue by using embedded system has become a hotspot of application. As representative of embedded system, the mainstream processors are represented by ARM9 have been more and more widely applied. Based on the above backgrounds, this paper describes the design and development processes of the image processing demonstration system which enables ＂independent landing for the small aircrafts＂ by taking the processor TMS320DM6446 of TI＇s first DSP＋ARM architecture as the development environment and using multithreading technology.
