Abstract :
We present an asynchronous circuit for an arbiter cell that can be used to construct cascaded multiway arbitration circuits. The circuit is completely speed-independent. It has a short response delay at the input request-grant handshake link due to both a) the propagation of requests in parallel with starting arbitration and b) the concurrent resetting of request-grant handshakes in different cascades of a request-grant propagation chain.<>
