%X 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.
