Member Function Documentation

void NoCScheduleProblem::addScheduleSwitchConstraint ( NoCScheduleSwitchConstraint & s ) [inline]

References scheduleSwitchConstraints.

Referenced by SetOfNoCScheduleProblems::SetOfNoCScheduleProblems().

void NoCScheduleProblem::constrainOtherSchedulingProblem ( NoCScheduleProblem * p )

constrainOtherSchedulingProblem () The function marks slots on links of the interconnect graph in the schedule problem p which it uses in its own schedule.

It is possible that the overlap between the schedules contains multiple periods of the source and/or destination schedule.

Here is the call graph for this function:

void NoCScheduleProblem::constructMessages	(	CNode *	messagesNode,
		InterconnectGraph *	archGraph
	)			`[private]`

constructMessages () The function constructs a list of all messages from an XML document.

References solvedFlag.

Referenced by constrainOtherSchedulingProblem(), NoCScheduler::markPreferedSlotsOnLinks(), and NoCScheduler::schedule().

void NoCScheduleProblem::markPreferedSlots ( InterconnectGraph * g )

markPreferedSlots () The function marks all slots in all links of the interconnect graph as prefered slots (with the maximal preference level - UINT_MAX) when this slot is used in the corresponding link of the interconnect graph g.
