| 摘要 |
A system for validating communications between a plurality of processors is disclosed. The system includes a plurality of loop back paths, and each of the loop back paths is coupled to a corresponding one of the plurality of processors. In addition, each loop back path is configured to attenuate one of a plurality of signals transmitted from each of the corresponding ones of the plurality of processors so as to generate a plurality of loop back signals. A plurality of signal transmission paths are configured to carry a corresponding one of the plurality of signals from one of the plurality of processors to another of the plurality of processors, and a plurality of comparators compare the plurality of loop back signals to the plurality of transmission signals so as to enable the validity of each of the plurality of signals to be assessed.
