entity Lvl2ProcessorTakes data from the Extractor to send then to Lvl2 after processing. |
The Lvl2Processor receives data from the Extractor (it's a push architecture which can be vetoed through the Lvl2ChainBusy output of the Lvl2Processor). It selects Muons belonging to a specific BC in a +/- 2BC wide window around the Lvl2 event ID. The selected candidates are then ordered according to their transverse momentum. Finally the candidates are sent to lvl2 in a formatted way: Most energetic candidates are sent first. A maximal number of candidates which is sent, can be programmed. The details of the output format can be found in the corresponding diagrams.
