An asynchronous low latency arbiter for Quality of Service (QoS) applications
T. Felicijan, W.J. Bainbridge, S.B. Furber
In this paper we present the construction of a self-timed, multiple-input, priority arbiter with lower latency than existing solutions. The arbiter also overcomes the problem of allowing a contender to obtain over 50% of the resource allocation in a self-timed system by using downstream knowledge to trigger the arbitration. The arbiter is especially suited to the provision of quality of service in a self-timed interconnect.
