A Pulsed Communication/Computation Framework for Analog VLSI Perceptive Systems
This paper reports on the main properties and some applications of a pulsed communication system specifically developed for the service of multichip perception schemes realized in analog VLSI. The project started with the goal to obtain biological-like connectivity among functional subsystems capable of processing sensory data in a collective fashion through several hierarchical layers and through convergence, divergence and fusion of data from different origins. As a consequence of the thin sheet organization of their biological counterparts, the realized subsystems consist almost invariably of several one- or two-dimensional arrays of cells. The output of every cell, its activity, is relevant to further processing and should be available for communication to the next layer.
