NEUROMORPHIC SIGNAL PROCESSING DEVICE FOR LOCATING SOUND SOURCE USING A PLURALITY OF NEURON CIRCUITS AND METHOD THEREOF

摘要

A kind of direction of the estimation sound source of neuromorphic signal processing unit, uses multiple neuron circuits. Embodiment includes: detection unit in multiple frequency bands of each frequency band, for detecting the detection of spiking, using detection neuron circuit correspond to a specific time it is poor, when the first signal and the second signal have specific time it is poor, and including it is identical input spike signal; The signal of multiple detection spikes output of the spiking of multiplexer unit output multi-channel multiplexing, which is poor in specific time corresponding to multiple frequency bands by multiple neuron circuits for these signals; The signal is exported with integration spike and is based on multiple multiplexing spikes corresponding to specific time difference, these signals correspond to multiple time differences. ;The 2014 of copyright KIPO submissions;[Reference numerals] ( 111,113) postpone neuron; ( 112,114) neuron is detected simultaneously; ( 121,122) it is multiplexed neuron; ( 131,132) neuron is integrated; (AA) frequency band; (BB) time difference
