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.
