The printed circuit board layout inspection methods are mostly based on local geometric information, therefore it is well suited to the cellular neural network (CNN) paradigm. Two layout errors are detected here namely, the breaks in the wires and some kind of short circuits. The designed analogic algorithms to solve the problems above were tested on real life examples using an experimental system based on our CNN-HAC1M digital multiprocessor add-on-board, with 1 million cell space and 2.0 /spl mu/s/cell/iteration speed.

Optical imaging is a technique of radiating light into biological tissue and generating images in order to observe and characterise its anatomy, condition, and function. In the present work, various research needs are examined to systematically develop a list of requirements for a powerful optical imaging research tool. Basing from the requirements, a new system that can match or exceed the capabilities of other existing systems in terms of speed, cost-effectiveness, flexibility and potential for growth is developed. As an enabling technology, this system and its future derivatives, can spur the rate of progress in optical imaging research and pave the way for future clinical use of the technology.

This paper describes the design of a fully programmable multimedia system. The system, which utilizes a single multimedia video processor (MVP), is capable of performing real-time MPEG video and audio encoding at SIF resolution, 30 frames per second. Support is provided for a windows environment, including a scalable video window for viewing decoded video sequences or monitoring video compression in real time. The system is also well suited to perform image processing, 2-D and 3-D graphics, and many other video and audio processing and compression algorithms.
The term multimedia implies the combination of many different forms of information including computer graphics, text, video and audio, along with data distribution mechanisms and storage systems that can provide such ...

UWGSP4 (University of Washington Graphics System Processor) consists of four parts: a parallel vector processor, a shared-memory system, an interconnection network, and a graphics subsystem. The parallel vector processor was provided mainly for imaging and general-purpose computing, whereas the main functions of the graphics subsystem are to generate realistic three-dimensional images and to draw the display screen. Among the four parts, the shared memory and the interconnection network were designed to fully support the parallel vector processor and graphics subsystem so as to yield high sustained performance. A discussion is presented of the architecture of UWGSP4, simulated performance figures for several imaging and graphics algorithms, and applications areas.< >

A description is given of the computer graphics aspects of two architectures designed for imaging and graphics. The two systems use parallel and pipelined architectures for high-performance graphics operations. UWGPSP3 uses only commercially available off-the-shelf chips, and consists of a TM34020 graphics system processor and four TMS34082 floating point coprocessors that can be configured into pipelined or SIMD modes depending on the algorithm. UWGSP4 uses dedicated ASIC chips for higher performance, and consists of two main computational parts: a parallel vector processor with 16 vector processing units, used mainly for image processing, and a graphics subsystem which utilizes a parallel pipelined architecture for image synthesis.< >
