Function Documentation

accumulate()

bool accumulate	(	AccumulateMap &	map,
		std::vector< module_t > const &	modules,
		FPGATrackSimMatrixAccumulator const &	acc
	)

Helper function for adding a track/accumulator to an accumulate map.

Parameters

map	- map to be added to
modules	- sector definition of the accumulator to be added
acc	- accumulator to be added

Returns

true if a new sector was just added, and false if acc was accumulated into an existing item.

Helper function for adding a track/accumulator to an accumulate map.

a single track) to an accumulate map.

Parameters

map	- map to be added to
modules	- sector definition of the accumulator to be added
acc	- accumulator to be added

Returns

true if a new sector was just added, and false if acc was accumulated into an existing item.
