Constructor & Destructor Documentation

ReservationTableFUResourceConflictDetector()

ReservationTableFUResourceConflictDetector::ReservationTableFUResourceConflictDetector

(

const TTAMachine::FunctionUnit &

fu

)

Constructor.

Parameters

fu	The function unit to detect conflicts for.

Exceptions

InvalidData

If the model could not be built from the given FU.

Member Function Documentation

advanceCycle()

bool ReservationTableFUResourceConflictDetector::advanceCycle ( )

virtual

Simulates a cycle advance and reports a conflict if detected.

Returns

False in case a conflict is detected, otherwise true.

Reimplemented from FUResourceConflictDetector.

Definition at line 74 of file ReservationTableFUResourceConflictDetector.cc.

                                                         {
    return advanceCycleInline();
}

Referenced by advanceCycle().

issueOperation()

bool ReservationTableFUResourceConflictDetector::issueOperation ( OperationID  id )

virtual

Issues an operation and reports a conflict if detected.

Parameters

id	The id of the operation to issue.

Returns

False in case a conflict is detected, otherwise true.

Reimplemented from FUResourceConflictDetector.

Definition at line 64 of file ReservationTableFUResourceConflictDetector.cc.

                                                                         {
    return issueOperationInline(id);
}

OperationID

id

)

Referenced by issueOperation().

operationID()

ReservationTableFUResourceConflictDetector::OperationID ReservationTableFUResourceConflictDetector::operationID ( const TCEString &  operationName ) const

virtual

Returns an operation id for the given operation.

Operation IDs are used in the interface for optimizing the access. This method converts OSAL Operations to operation IDs.

Parameters

operation

The OSAL Operation to find ID for.

Returns

The operation ID.

Exceptions

KeyNotFound

if the operation of given name couldn't be found

Reimplemented from FUResourceConflictDetector.

Definition at line 89 of file ReservationTableFUResourceConflictDetector.cc.

                                          {
 
    // find the index of the operation in the FU, it corresponds to the
    // operation ID
    for (int i = 0; i < fu_.operationCount(); ++i) {
        if (StringTools::ciEqual(fu_.operation(i)->name(), operationName)) {
            return i;

Here is the call graph for this function:

reset()

void ReservationTableFUResourceConflictDetector::reset ( )

virtual

Sets the state of the detector to its initial state.

This means that the FU state is assumed to be what it is in powerup.

Reimplemented from FUResourceConflictDetector.

Definition at line 108 of file ReservationTableFUResourceConflictDetector.cc.
