static ushort_v	CalculateHitWeight (ushort_v numberOfHits, ushort_v unique)

Detailed Description

Data abstraction class for the Slice Tracker.

Different architectures implement this for the most efficient loads and stores. All access to the data happens through inline functions so that access to the data has no extra costs.

ushort_v AliHLTTPCCASliceData::CalculateHitWeight	(	ushort_v	numberOfHits,
		ushort_v	unique
	)

inlinestatic

The hit weight is used to determine whether a hit belongs to a certain tracklet or another one competing for the same hit. The tracklet that has a higher weight wins. Comparison is done using the the number of hits in the tracklet ( the more hits it has the more it keeps ). If tracklets have the same number of hits then it doesn't matter who gets it, but it should be only one. So a unique number ( row index is good ) is added in the least significant part of the weight

int AliHLTTPCCASliceData::ClusterDataIndex	(	const AliHLTTPCCARow &	row,
		int	hitIndex
	)		const

inline

Returns the index in the original AliHLTTPCCAClusterData object of the given hit

ushort_v AliHLTTPCCASliceData::FirstHitInBin	(	const AliHLTTPCCARow &	row,
		ushort_v	binIndexes
	)		const

inline

For a given bin index, content tells how many hits there are in the preceding bins. This maps directly to the hit index in the given row.

Parameters

binIndexes in the range 0 to row.Grid.N + row.Grid.Ny + 3.
