Cheops: a reconfigurable data-flow system for video processing

The Cheops Imaging System is a compact, modular platform for acquisition, processing, and display of digital video sequences and model-based representations of moving scenes, and is intended as both a laboratory tool and a prototype architecture for future programmable video decoders. Rather than using a large number of general-purpose processors and dividing up image processing tasks spatially, Cheops abstracts out a set of basic, computationally intensive stream operations that may be performed in parallel and embodies them in specialized hardware. We review the Cheops architecture, describe the software system that has been developed to perform resource management, and present the results of some performance tests.>
