项目摘要

A new multi-processor architecture has been developed for high-speed and efficient integrated processing of large amount image data such as satellite images. This system architecture is comprised with newly developed processors which are called pipelined MIMD processors, shared memory and multi-stage interconnection network designed for high speed parallel image processing.For the total efficient instruction and data flows under memory access delays commonly taking place on a multi-stage interconnection network machine, the new architecture of pipelied MIMD processor is proposed for this system. In this mechanism, multiple independent instruction sequences can run parallel in each single processor under pipelined controls. It enables wide variety of effective parallel image processings from low level to higher levels.The performance of the system has been evaluated with a variety of simulations and a fully detailed design of the pilot system with this architecture. Their results promises that a high performance processor can be realized in a small sized machine.With the development of the hardware architecture, algorithms for efficient image processing have been also studied. New image processing techniques for an analysis of under-ground radar images, a shape analysis of planar figures, three dimensional shape recognitions, digital image measurements and so on have been developed.

一种新的多处理器体系结构已经被开发出来，用于高速、高效地综合处理大量图像数据，例如卫星图像。该体系结构由新开发的流水线MIMD处理器、共享存储器和为高速并行图像处理而设计的多级互连网络组成，针对多级互连网络机器在内存访问延迟下指令和数据流的总效率，提出了一种新的流水线MIMD处理器体系结构。在该机制中，多个独立的指令序列可以在流水线控制下在每个单处理器中并行运行。它实现了从低级到高级的各种有效的并行图像处理。系统的性能已经通过各种仿真和基于该体系结构的试点系统的详细设计进行了评估。随着硬件体系结构的发展，高效的图像处理算法也得到了研究。在井下雷达图像分析、平面图形形状分析、三维形状识别、数字图像测量等方面，出现了新的图像处理技术。
