public class CUDAObjectTrackerControl
extends EventFilter2D

Allows control of remote CUDA process for filtering jAER data.

This filter does not process events at all. Rather it opens a TCP stream socket connection to a remote (maybe on the same machine) process which is a CUDA GPGPU program which accepts AEs from jAER and which sends its output back to jAER for visualization.

The stream socket works with text command lines as though it were a terminal.

Constructor Detail

CUDAObjectTrackerControl

public CUDAObjectTrackerControl(AEChip chip)

Method Detail

doKillCUDA

public void doKillCUDA()

doLaunchCUDA

public void doLaunchCUDA()

Launches the CUDA process, then sends parameters to it. When the CUDA process is launched externally, we don't know if it's running and it will not have commands from us initially.

doSelectCUDAExecutable

public void doSelectCUDAExecutable()

doSendParameters

public void doSendParameters()

filterPacket

public EventPacket<?> filterPacket(EventPacket<?> in)

Reconstructs a raw event packet, sends it to jaercuda, reads the output from jaercuda, extracts this raw packet, and then returns the events.

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packets.

Returns:

the output packet.

setFilterEnabled

public void setFilterEnabled(boolean yes)

Description copied from class: EventFilter2D

Resets the filter

Overrides:

setFilterEnabled in class EventFilter2D

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter
