estimateArea()

bool CostEstimator::FUCostEstimationPlugin::estimateArea ( const TTAMachine::FunctionUnit &  architecture, const IDF::FUImplementationLocation &  implementation, AreaInGates &  area, HDB::HDBManager &  hdb  )

virtual

Estimates the area of the given function unit.

Parameters

architecture	The FU architecture of which area to estimate.
implementation	(The location of) the implementation of FU. Can be an instance of NullFUImplementationLocation.
area	The variable to store the area estimate into.

Returns

True only if area could be estimated successfully.

Reimplemented in InterpolatingFUEstimator, and StrictMatchFUEstimator.

estimateEnergy()

bool CostEstimator::FUCostEstimationPlugin::estimateEnergy ( const TTAMachine::FunctionUnit &  architecture, const IDF::FUImplementationLocation &  implementation, const TTAProgram::Program &  program, const ExecutionTrace &  traceDB, EnergyInMilliJoules &  energy, HDB::HDBManager &  hdb  )

virtual

Estimates the energy consumed by the given function unit when running the given program.

Parameters

architecture	The FU architecture of which area to estimate.
implementation	(The location of) the implementation of FU. Can be an instance of NullFUImplementationLocation.
program	The program of which energy to calculate.
traceDB	The simulation trace database of the program running in the target architecture.
energy	The variable to store the energy estimate into.

Returns

True only if energy could be estimated successfully.

bool CostEstimator::FUCostEstimationPlugin::estimateMaximumComputationDelay ( const TTAMachine::FunctionUnit &  architecture, const IDF::FUImplementationLocation &  implementation, DelayInNanoSeconds &  computationDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the maximum computation delay of the given function unit.

The maximum computation delay is the longest stage in the FU unit's pipeline. It's used mainly for calculating the maximum clock frequency of target architecture.

Parameters

architecture	The FU architecture of which area to estimate.
implementation	(The location of) the implementation of FU. Can be an instance of NullFUImplementationLocation.
computationDelay	The variable to store the delay estimate into.

Returns

True only if computation delay could be estimated successfully.

bool CostEstimator::FUCostEstimationPlugin::estimatePortReadDelay ( const TTAMachine::FUPort &  port, const IDF::FUImplementationLocation &  implementation, DelayInNanoSeconds &  outputDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the output delay of the given function unit port.

Parameters

port	The FU port of which output delay to estimate.
implementation	(The location of) the implementation of FU. Can be an instance of NullFUImplementationLocation.
outputDelay	The variable to store the delay estimate into.

Returns

True only if output delay could be estimated successfully.

bool CostEstimator::FUCostEstimationPlugin::estimatePortWriteDelay ( const TTAMachine::FUPort &  port, const IDF::FUImplementationLocation &  implementation, DelayInNanoSeconds &  inputDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the input delay of the given function unit port.

Parameters

port	The FU port of which input delay to estimate.
implementation	(The location of) the implementation of FU. Can be an instance of NullFUImplementationLocation.
inputDelay	The variable to store the delay estimate into.

Returns

True only if input delay could be estimated successfully.
