In this paper we introduce a VLSI priority encoder that uses a novel priority lookahead scheme to reduce the delay for the worse case operation of the circuit, while maintaining a very low transistor count. The encoder's topmost input request has the highest priority ; this priority descends linearly. Two design approaches for the priority encoder are presented, one without a priority lookahead scheme and one with a priority lookahead scheme. For an N-bit encoder, the circuit with the priority… CONTINUE READING
