Neuromorphic mixed-signal circuitry for Asynchronous Pulse Processing

Abstract

We demonstrate a software reconfigurable mixed-signal Printed Circuit Board (PCB) prototype and a custom mixed-signal Application Specific Integrated Circuit (ASIC) prototype of a cognitive signal processor using neuromorphic methods to perform adaptive nonlinear filtering based real-time wideband signal processing algorithms. The cognitive processor effectively implements a trending computing paradigm called Reservoir Computer (RC). Hardware implementation of the RC is achieved by a novel analog signal processor architecture called the Asynchronous Pulse Processor (APP).
