Abstract: A self-contained chip set architecture for ANN systems, based on back-propagation model with full-connectivity topology, and on-chip learning and refreshing, based on analog chip set technology providing self-contained synapse and neuron modules with fault tolerant neural computing, capable of growing to any arbitrary size as a result of embedded electronic addressing. Direct analog and digital I/O ports allow real-time computation and interface communication with other systems including digital host of any bus bandwidth. Scalability is provided, allowing accommodation of all input/output data sizes and different host platform.
