Title: Priority encoder circuit

Abstract: A priority encoder circuit (10, 60) is provided. The priority encoder circuit (10, 60) includes a plurality of inputs (38, 90) and outputs (40, 92). The number of inputs (38, 90) equals the number of outputs (40, 92), and each input (38, 90) corresponds to one output. Each input (38, 90) receives a signal that indicates whether the input (38, 90) has been selected. The priority encoder circuit (10, 60) also includes circuitry (50, 100) that generates a signal at the output (40, 92) corresponding to the input (38, 90) having the highest priority that receives the selection signal.
