嵌入式操作系统在实时图像处理系统中的应用

The Application of Embedded Operating System in Real-time Image Processing System

以多片ADSP2 10 6 0构成的图像处理系统为硬件平台 ,借助Virtuoso 4 .2提供的微内核构造了一个嵌入式系统软件 ,介绍了系统中任务调度、资源管理、并发处理、中断响应、数据通信等实现方式。最后 ,针对某些图像处理算法进行了实验 ,并测试了系统性能指标 ,实验结果表明提出的方案实现方便、开发快捷、性能稳定可靠 ,可在实时图像处理系统中得到广泛应用。

For the image processing system which consists of multiple DSPs ADSP21060, an embedded system software based on the micro kernel provided by Virtuso 4.2 is designed. The implementation of the task schedule, resources management, parallel processing, interrupt acknowledgment and data communication in the system is described in this paper. In terms of some image processing algorithms, the performance of the system is tested. It showed that the system software proposed is easy to realize and develop. It is also steady and reliable and therefore this approach is suggested to be used widely in the image processing system.
