Abstract
A reconfigurable priority encoding arrangement and method. In various embodiments, the invention identifies, from a plurality of input signals, a highest priority signal that is in a selected state. A priority routing block is implemented on a programmable logic device (PLD). The routing block has a plurality of input ports arranged to receive the respective input signals and a plurality of output ports respectively coupled to the input ports. A priority encoder is also implemented on the PLD and has input ports respectively coupled to the output ports of the priority routing block. Each input port has a priority relative to others of the input ports. The priority encoder is configured to generate an address signal that identifies the input signal having a highest priority and that is in the selected state.
