estimateArea()

bool CostEstimator::RFCostEstimationPlugin::estimateArea ( const TTAMachine::BaseRegisterFile &  architecture, const IDF::RFImplementationLocation &  implementation, AreaInGates &  area, HDB::HDBManager &  hdb  )

virtual

Estimates the area of the given RF.

Parameters

architecture	The RF architecture of which area to estimate.
implementation	(The location of) the implementation of RF.
area	The variable to store the area estimate into.

Returns

True only if area could be estimated successfully.

Reimplemented in InterpolatingRFEstimator, and StrictMatchRFEstimator.

estimateEnergy()

bool CostEstimator::RFCostEstimationPlugin::estimateEnergy ( const TTAMachine::BaseRegisterFile &  architecture, const IDF::RFImplementationLocation &  implementation, const TTAProgram::Program &  program, const ExecutionTrace &  traceDB, EnergyInMilliJoules &  energy, HDB::HDBManager &  hdb  )

virtual

Estimates the energy consumed by the given RF when running the given program.

Parameters

architecture	The RF architecture of which area to estimate.
implementation	(The location of) the implementation of RF. 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 which can be used in the estimation algorithm.
energy	The variable to store the energy estimate into.

Returns

True only if energy could be estimated successfully.

Reimplemented in StrictMatchRFEstimator, and InterpolatingRFEstimator.

estimateMaximumComputationDelay()

bool CostEstimator::RFCostEstimationPlugin::estimateMaximumComputationDelay ( const TTAMachine::BaseRegisterFile &  architecture, const IDF::RFImplementationLocation &  implementation, DelayInNanoSeconds &  computationDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the maximum "computation delay" of the given RF.

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

Parameters

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

Returns

True only if computation delay could be estimated successfully.

Reimplemented in InterpolatingRFEstimator, and StrictMatchRFEstimator.

estimatePortReadDelay()

bool CostEstimator::RFCostEstimationPlugin::estimatePortReadDelay ( const TTAMachine::RFPort &  port, const IDF::RFImplementationLocation &  implementation, DelayInNanoSeconds &  outputDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the output delay of the given RF port.

Parameters

port	The RF port of which output delay to estimate.
implementation	(The location of) the implementation of RF.
outputDelay	The variable to store the delay estimate into.

Returns

True only if output delay could be estimated successfully.

Reimplemented in InterpolatingRFEstimator, and StrictMatchRFEstimator.

estimatePortWriteDelay()

bool CostEstimator::RFCostEstimationPlugin::estimatePortWriteDelay ( const TTAMachine::RFPort &  port, const IDF::RFImplementationLocation &  implementation, DelayInNanoSeconds &  inputDelay, HDB::HDBManager &  hdb  )

virtual

Estimates the input delay of the given RF port.

Parameters

port	The RF port of which input delay to estimate.
implementation	(The location of) the implementation of RF.
inputDelay	The variable to store the delay estimate into.

Returns

True only if input delay could be estimated successfully.

Reimplemented in InterpolatingRFEstimator, and StrictMatchRFEstimator.
