Computing with waves: the analogic cellular computing paradigm for electrons, photons, and molecules
Tamás Roska · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2000
An emerging computing paradigm is presented bridging the gap between many novel technologies using photons, electrons, and molecules for signal processing. Computing with waves is the essence of the analogic cellular computer, having elementary instructions as PDE solvers on a grid. The formal computer architecture, the CNN Universal Machine, has been implemented in CMOS, in optical and in molecular level technologies. The standard CMOS implementation is a single chip visual microprocessor with TeraOPS speed. The heart of the matter is described by a formal framework where the data are flows. The only discrete entity is the space. Recent developments as well as the computational infrastructure are briefly summarized.
