public class FinishCondition

extends Conditions

The status when a macro task finish execution. This condition is used by the dynamic scheduler.

Field Summary

protected int	elemSize The size of the elements of this condition
protected MdfEnvironment	env
protected boolean[]	isReady The condition whether the bit is ready
protected MacroFlowGraph	mfg The current macro flow graph
protected int[][]	vector The conditions which set into the executable conditions when the macro task finishes executing
protected int	vectSize Ths size of the bit vector

Constructor Summary

protected void	showVector(java.lang.String name) Debug print of the bit vector.
java.lang.String	toString() Get the string image of the bit vector.
java.lang.String	toString(MacroTask mt) Get the string image of the bit vector which is belong to the specified macro task.

Constructor Detail

FinishCondition

public FinishCondition(MdfEnvironment e,
                       MacroFlowGraph g)

Constructor:

Parameters:

e - The environment of the MDF module

g - The current macro flow graph

Method Detail

finishCond

Stmt finishCond(MacroTask src,
                MacroTask dst)

Get the HIR statement which means the conditions when the macro task `src' is finished. If the macro task `dst' is not equal to `null', that means `src' includes a conditional branch and `dst' is decided as the next macro task.

Parameters:

src - The macro task which is finished

dst - The macro task which is decided as the next macro task

Returns:

The HIR statement which means a report the current condition to the scheduler

bitVector

protected int[] bitVector(int id)

Get the bit vector which means the condition when the specified macro task is finished executing.

Parameters:

id - The unique number of each macro tasks

Returns:

The bit vector which means the condition for the dynamic scheduler

showVector

protected void showVector(java.lang.String name)

Debug print of the bit vector.

Parameters:

name - The name of the bit vector

toString

public java.lang.String toString()

Get the string image of the bit vector.

Returns:

The string image of the bit vector

toString

public java.lang.String toString(MacroTask mt)

Get the string image of the bit vector which is belong to the specified macro task.

Parameters:

mt - The target macro task

Returns:

The string image of the bit vector
