isStaticNet

public boolean isStaticNet()

Returns:

Returns true if this buffer uses staticNet.

setStaticNet

public void setStaticNet(boolean staticNet)

Parameters:

staticNet - The staticNet to set.

redundant

public boolean redundant()

Specified by:

redundant in class OffChipBuffer

getNonRedundant

public OffChipBuffer getNonRedundant()

Description copied from class: OffChipBuffer

if this buffer is redundant return the first upstream buffer that is not redundant, return null if this is a input->filter buffer with no input or a filter->output buffer with no output

Specified by:

getNonRedundant in class OffChipBuffer

calculateSize

protected void calculateSize()

Specified by:

calculateSize in class OffChipBuffer

getDstIntraBuf

public static IntraSliceBuffer getDstIntraBuf(Slice t)

Parameters:

t - a slice.

Returns:

The intrasliceBuffer between the last filter and the outputslicenode

getSrcIntraBuf

public static IntraSliceBuffer getSrcIntraBuf(Slice t)

Parameters:

t - a slice.

Returns:

The intraslicebuffer between the inputslicenode and the first filterslicenode
