A two-stage arbitration scheme is employed to arbitrate access to the command bus. The first arbitration stage is used to arbitrate between command requests issued by masters in a given cluster. The second arbitration stage is used to arbitrate between winning first stage command requests. One ...

The second-type devices practice a round robin arbitration scheme, but the first type devices do not. According to the round-robin scheme, a second-type device which wins an arbitration asserts its ID on the system bus, each second- type device seeking to arbitrate compares its ID with that...
This paper proposes a round-robin based arbitration scheme for a CICB packet switch that provides 100% throughput for several admissible traffic patterns, including those with uniform and nonuniform distributions, using one-cell crosspoint buffers and no speedup. The presented scheme uses adaptable-...
This paper presents a Time efficient and an area efficient, two different ways of designing Round Robin Arbitration for different applications. An arbiter is a logical element which is helpful in selecting the order of access to a shared multi-master bus system. For each bus cycle, which multi...

A method and apparatus for a round robin resource arbitration scheme is described. An apparatus to provide round robin token arbitration comprises at least two token arbiters, each token arbiter associated with a node to which at least two sub-trees are connected, each sub-tree comprising a tok...
Various methods and apparatuses are described for an arbitration unit that implements a round robin policy. Each requesting device has an equal chance of accessing a shared resource based upon a current request priority assigned to that requesting device. The arbitration unit includes at least a stat...
