摘要： 阐述了一种新型动态结构可重构技术及其在分布式图像处理系统中的应用。以并行处理中的流水线技术和空间并行技术为基础，结合二者的优点提出一种可动态重构的结构模型，通过决策代价函数进行最优判决，将分解后算法任务最佳地映射到体系结构中去，在时间维和空间维上提高整个系统的实时并行处理性能。在实际环境中验证了该动态技术的正确性和优越性。

Abstract: A new dynamic reconfiguration technique and its applications in distributed image processing system are introduced. Based on the pipeline and spatial parallel processing techniques, the new technique combines merits of the two and proposes a dynamic reconfiguration model. In order to improve real time performance in parallel processing system in time and space, optimized judgment is made by the decision cost function, which makes the disassembled arithmetic task best mapped to system architectures. The dynamic technique is verified correct and ascendant in actual system.

Key words: dynamic reconfiguration, pipeline, spatial parallelism, decision cost function
