Detailed Description

L1 Global Muon Trigger Cancel-Out Unit.

It compares (attempts to match) muons in the overlap region in order to cancel out duplicates. The following four instances exist:

                  INPUTS

idx unit where mu1 mu2

0 DT/CSC brl DT CSC 1 CSC/DT fwd CSC DT 2 bRPC/CSC brl bRPC CSC 3 fRPC/DT fwd fRPC DT (mine) (other chip)

The first input muons are direct inputs to the chip where the COU is located, while the second muons are CSC or DT muon from the other Logic FPGA.

Along with the input muons to be compared the COU accesses information on whether the input muons are matched with a cnadiate from the complementary system in the respective main matcher.

The output are cancel-bits which indicate whether to delete one of the inputs.
