Abstract:
PURPOSE: A device for transmitting/receiving a spike event in a neuromorphic chip and a method thereof are provided to synchronize and transmit address information and timing information of a neuron in which the spike event is generated, thereby simplifying the structure of a transmitter in the neuromorphic chip. CONSTITUTION: An address output unit(260) successively outputs addresses to an address bus. Spike sensing units(221-223) sense a spike generated in neurons. When the spike is received, output point sensing units(231-233) correspond to the spike sensing units and sense the earliest point of time when the outputted address is identical with an address of a neuron outputting the spike. A strobe output unit(250) outputs a strobe showing timing information when the spike is generated.

PURPOSE: A depth information method and an apparatus thereof are provided to accurately measure depth information and to output a light-pulse to a subject. CONSTITUTION: A log node voltage increases greater than a first threshold value after activating a first control signal. A comparison outputting unit(220) outputs a comparison node voltage having a second threshold value. At least one discharging unit(230) discharges a previously charged output node voltage according to a predetermined rule in case the output of the comparison outputting unit indicates the second threshold value.

PURPOSE: A moving recognition apparatus and method thereof are provided to skip an image pre-processing process for recognizing a mobile object by tracking the movement of the mobile object. CONSTITUTION: An image sensor(111) outputs events by sensing the moving part of a subject. A movement tracking unit(120) tracks the movement of the mobile object by using the relational rate of the event. A motion pattern determination unit(130) determines the moving pattern of a moving part. A parallax calculation unit calculates parallax between the image sensors by using the histogram of the events outputted by the image sensor. A synthesis unit synthesizes the events based on the parallax.
