  abstract= "In this paper we will present the architecture of SYDAMA-2
     and its programming environment as well as early experiences
     gained in developing applications with it. The goal of this
     project was to find and develop an architecture that was
     capable of executing entire applications in the domain of
     real time image processing. The architecture consists of two
     parts: one for low level preprocessing and one for
     intermediate and high level postprocessing.The preprocessing
     subsystem is based on the direct mapping of static dataflow
     graphs onto hardware. While highly specialized processing
     elements can be implemented for reasons of efficiency most
     of them consist of lookup tables for the sake of their
     processing speed and flexibility. All of them are controlled
     by a transputer that does the housekeeping.The processing
     elements are interconnected through a communication network
     which is realized as a pipelined multichannel ringbus that
     is fully reconfigurable on the fly. The bandwidth is large
     enough to carry several video streams and because the buses
     can be subdivided at every stage, the overall bandwidth
     effectively scales with the number of stages (processing
     elements).The postprocessing subsystem consists of a
     standard off the shelf transputer network that is closely
     connected to the low level subsystem.The programming
     environment consists of a number of tools that cover the
     different stages of programming an application: The low
     level programming interface for the image processing
     subsystem, a configuration tool and the runtime support that
     controls and interconnects the different tasks."
