along with itst mapper DPSS (A Datapath Synthesis System) for the rDPA (reconfigurable Datapath Array) is a generalization of the systolic array. The systolic array is a coarse grain pipe network. During the 80ies and later the research in systolic arrays had been dominated by mathematicians. Until the mid' 90ies the progress of this area had stalled because of the mind set of a typical mathematician. For a hammer almost everything in the world looks like a nail. For a typical mathematician almost everything in the world has looked like an algebraic problem, so that all systolic array synthesis methods of that time have been based on linear projection, so that systolic array usage had been restricted to applications with strictly regular data dependencies. These classical systhesis methods have yielded only uniform arrays permitting only linear pipes .
It has been the achievement of Rainer Kress to discard such algebraic synthesis methods, and, to replace it with simulated annealing [x]. By this fundamental paradigm shift Rainer Kress has removed the restrictions (see above) by supporting also non-uniform arrays including also any wild wild structures of the pipe network like, for instance, with zig-zag, spiral, fork/join and any free form pipes. By this generalization it makes sense to have reconfigurable pipe networks: rDPAs (reconfigurable Datapath Arrays).
