All Implemented Interfaces:

java.io.Serializable

public class DVS320
extends AERetina
implements java.io.Serializable

Describes DVS320 retina and its event extractor and bias generator. Two constructors ara available, the vanilla constructor is used for event playback and the one with a HardwareInterface parameter is useful for live capture. setHardwareInterface(net.sf.jaer.hardwareinterface.HardwareInterface) is used when the hardware interface is constructed after the retina object. The constructor that takes a hardware interface also constructs the biasgen interface.

The DVS320 features 320x240 pixels, a fully configurable bias generator, and a configurable output selector for digital and analog current and voltage outputs for characterization. The output is word serial and includes an intensity neuron which rides onto the other addresses. DVS320 is built in UMC18 CIS process and has 14.5u pixels.

Constructor Detail

DVS320

public DVS320()

Creates a new instance of DVS320.

DVS320

public DVS320(HardwareInterface hardwareInterface)

Creates a new instance of DVS320

Parameters:

hardwareInterface - an existing hardware interface. This constructer is preferred. It makes a new DVS320Biasgen object to talk to the on-chip biasgen.

Method Detail

setHardwareInterface

public void setHardwareInterface(HardwareInterface hardwareInterface)

overrides the Chip setHardware interface to construct a biasgen if one doesn't exist already. Sets the hardware interface and the bias generators hardware interface

Overrides:

setHardwareInterface in class Chip

Parameters:

hardwareInterface - the interface
