Ordered arbiters
Alexander I. Bystrov, Alex Yakovlev · Electronics Letters · 1999
The granting of requests in the order of their arrival is not satisfied in existing 1/n arbiters, such as token rings, tree arbiters and networks of two-way arbiters. The proposed solution stores pending grants in a FIFO, thus maximally preserving the request order, improves fairness and offers lower metastability rate.
