Abstract
A system for identifying asserted signals includes a plurality of input ports, a priority encoding module, and a match module. The plurality of input ports receive one of a plurality of input signals. The priority encoding module is coupled to the plurality of input ports and outputs a signal indicating a highest-priority input signal that is asserted. The match module is also coupled to the plurality of input ports and receives a plurality of match detect signals from the priority encoding module. Each match detect signal is associated with a particular input signal and indicates whether another input signal having a higher-priority than the associated input signal is asserted. The match module also generates a multiple match signal based on the input signals and the match detect signals. The multiple match signal indicates whether more than one of the input signals is asserted.
