◆ CostDBEntryStatsFU() [1/3]

CostDBEntryStatsFU::CostDBEntryStatsFU	(	double	areaData,
		double	delayData
	)

Constructor.

Parameters

areaData	area.
delayData	delay.

Definition at line 48 of file CostDBEntryStatsFU.cc.

                                                                         :

◆ CostDBEntryStatsFU() [2/3]

CostDBEntryStatsFU::CostDBEntryStatsFU	(	const CostDBEntryStatsFU &	stats1,
		const CostDBEntryStatsFU &	stats2,
		double	coefficient
	)

Constructor.

Combines two statistics into one using coefficient as a weighting factor on interpolating the statistics. For example, if weighting factor is 0.4, the first area 100 and the second 200, area of new statistics will be 140. delay and energy will be handled similarly.

Parameters

stats1	First statistics.
stats2	Second statistics.
coefficient	Weighting factor.

Here is the call graph for this function:

◆ energyActive()

double CostDBEntryStatsFU::energyActive ( ) const

virtual

Returns the energy of an entry in an active cycle.

The function will fail since function units do not have unambiguous energy for the whole unit but separately for each operation.

Returns: The energy of an entry in an active cycle.

Exceptions

WrongSubclass	An illegal function was called for this instance.
KeyNotFound	Never thrown by this function.

Reimplemented from CostDBEntryStats.

Definition at line 100 of file CostDBEntryStatsFU.cc.

     throw WrongSubclass(__FILE__, __LINE__, 
             "CostDBEntryStatsFU::energyActive");
     return 0.0; // stupid return statement to make compiler quiet
 }

◆ energyOperation()

double CostDBEntryStatsFU::energyOperation ( const std::string & name ) const

virtual

Returns the energy of an entry when given operation is executed.

Parameters

name	name of the operation.

Returns: The energy of an entry when given operation is executed.

Exceptions

WrongSubclass	Never thrown by this function.
KeyNotFound	No energy matching the string found.

Here is the call graph for this function:

◆ hasEnergyOperation()

bool CostDBEntryStatsFU::hasEnergyOperation ( const std::string & name ) const

virtual

Checks whether the energy exists for the given operation.

Parameters

name	name of the operation.

Returns: True if the energy exists for the given operation.

Exceptions
