Dynamic Adaptive Neural Network Arrays (DANNAs) are neuromorphic systems that exhibit spiking behaviors and can be designed using evolutionary optimization. Array elements are rapidly reconfigurable and can function as either neurons, synapses or fan-out elements with programmable interconnections and parameters. Currently, DANNAs are implemented using Field Programmable Gate Arrays (FPGAs) and are constrained in capacity and performance by this technology. To alleviate these constraints and introduce new and improved features, a semi-custom Very Large Scale Integration (VLSI) design has been created. This VLSI design improves upon the FPGA implementations in three key areas: 50x improvement in element capacity, 10x improvement in clock speed, and a significant reduction in power consumption. Finally, the VLSI design allows for near real time monitoring of the individual elements in the array.
