<title>Computer/Display Architectures For Image Processing</title>

Abstract

Computer-based image processing and display capabilities can be provided by many different architectures with varying degrees of efficiency and complexity. This paper provides a survey of the capabilities of hardware currently available in the commercial market and describes several experimental image processing systems exhibiting a number of unique fea-tures. A new integrated display/processor architecture is also suggested which, when compared to existing systems, offers considerably enhanced performance without substantial increases in hardware complexity. This approach features a memory-centered design in which a multiported memory is shared between the processor and display, memory is interleaved using skewed storage techniques, and dynamic reconfiguration of the memory and interface is provided. The advantages of this architecture over the standard computer plus add-on display for operations such as image compression, multispectral classification, digital filtering, and image display are described.
