The following 0009 * four instances exist: 0010 * 0011 * INPUTS 0012 * idx unit where mu1 mu2 0013 * --------------------------------------- 0014 * 0 DT/CSC brl DT CSC 0015 * 1 CSC/DT fwd CSC DT 0016 * 2 bRPC/CSC brl bRPC CSC 0017 * 3 fRPC/DT fwd fRPC DT 0018 * (mine) (other chip) 0019 * 0020 * The first input muons are direct inputs to the chip where the 0021 * COU is located, while the second muons are CSC or DT muon from 0022 * the other Logic FPGA. 0023 * 0024 * Along with the input muons to be compared the COU accesses information 0025 * on whether the input muons are matched with a cnadiate from the 0026 * complementary system in the respective main matcher. 0027 * 0028 * The output are cancel-bits which indicate whether to 0029 * delete one of the inputs. 0030 * 0031 */ 0032 // 0033 // 0034 // Author : 0035 // H.
