public class DCT4x4dcextends VisualSim.actor.TypedAtomicActor

Calculate the discrete cosine transform(DCT) of dc coefficients of Y components. It uses 2x2 integer transform using in H.264 standard. Input block should have two dimensions by 4x4 integer block. The output port will have a 4x4 integer block of the result.

Since:
VisualSim 7.0

Field Detail

input

public VisualSim.actor.TypedIOPort input

Input for tokens. This is a 2x2 integer block, and its type is integer matrix.

output

public VisualSim.actor.TypedIOPort output

Output port. This is a result for calculating the DCT of the 2x2 integer block.

Constructor Detail

DCT4x4dc

public DCT4x4dc(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.
