Video Processing with the Princeton Engine at NIST

摘要

The document describes the NIST program in digital processing, including a newly created Image Processing Laboratory at NIST that is available to governmental, industrial, and academic researchers working on digital image processing. The centerpiece of the laboratory is a video supercomputer, the Princeton Engine, designed and constructed by the David Sarnoff Research Center. The engine provides real-time video and image-processing capability, accepting a variety of video formats over multiple wideband input channels and outputting real-time video for immediate viewing. Because the Engine is programmable, it is possible to use it to evaluate prototypes of image processing components rapidly and efficiently. The hardware capabilities of the Princeton Engine are described as well as the available supporting video equipment in the Laboratory. Two programming examples are included to demonstrate the unusual programming environment and 'language' used to program the Engine. Appendices list the available predefined library modules, and the processor assembly language instructions.
