Constructor & Destructor Documentation

DCMFUResourceConflictDetector()

DCMFUResourceConflictDetector::DCMFUResourceConflictDetector

(

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 DCMFUResourceConflictDetector::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 79 of file DCMFUResourceConflictDetector.cc.

                                            {
    return advanceCycleInline();
}

issueOperation()

bool DCMFUResourceConflictDetector::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 69 of file DCMFUResourceConflictDetector.cc.

                                                            {

id

)

Referenced by issueOperation().

operationID()

DCMFUResourceConflictDetector::OperationID DCMFUResourceConflictDetector::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.

Reimplemented from FUResourceConflictDetector.

                                          {
 
    // find the index of the operation in the FU, it corresponds to the
    // operation ID

        if (StringTools::ciEqual(fu_.operation(i)->name(), operationName)) {
            return i;
        }

}

Here is the call graph for this function:

reset()

void DCMFUResourceConflictDetector::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.
