public class IDCT4x4dcextends VisualSim.actor.TypedAtomicActor

Calculate the sum of absolute difference(SAD) between two blocks. Each input block should have two dimensions by rectangle block(16 by 16, 8 by 8, etc.). The output port will have the result of SAD.

Since:
VisualSim 7.0

Field Detail

input

public VisualSim.actor.TypedIOPort input

Input for tokens to be a part of previous frame. This is a single port, and its type is 2D array.

output

public VisualSim.actor.TypedIOPort output

Output port. This is a result for calculating sum of absolute differences between ImgBlockA and ImgBlockB. The type is inferred form the connections.

Constructor Detail

IDCT4x4dc

public IDCT4x4dc(VisualSim.kernel.CompositeEntity container,
java.lang.String name)
throws VisualSim.kernel.util.IllegalActionException,
VisualSim.kernel.util.NameDuplicationException

Construct an actor in the specified container with the specified name.

Parameters:
container - The container.
name - The name of this adder within the container.
Throws:
VisualSim.kernel.util.IllegalActionException - If the actor cannot be contained by the proposed container.
VisualSim.kernel.util.NameDuplicationException - If the name coincides with an actor already in the container.

Method Detail

clone

public java.lang.Object clone(VisualSim.kernel.util.Workspace workspace)
throws java.lang.CloneNotSupportedException

Override the base class to set type constraints on the ports.
Overrides:

clone in class VisualSim.actor.AtomicActor

Parameters:

workspace - The workspace into which to clone.
Returns:
A new instance of AddSubtract.
Throws:
java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.
