Toward a digital neuromorphic pitch extraction system

This paper presents the design of a biologically based signal processing system implemented using standard digital inferior colliculus (IC) technology. The four-stage AM detection system is a step toward a full-pitch detection system and based on known mammalian physiology. The system is operational and has been successfully realized in field programmable grid array (FPGA) technology. Details of the system architecture, its operating principles, and the design decisions necessary to realize successfully neuromorphic systems in digital technology are given.
