A priority encoder is a digital circuit that encodes multiple binary inputs into a smaller set of binary outputs, prioritizing the highest-order active input. It detects the highest-order active input and generates a binary code representing its position, ignoring lower-priority inputs. Priority encoders are commonly used in systems where multiple input sources need to be prioritized, such as interrupt controllers and data selection circuits.
