Abstract
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 state block that includes a plurality of state registers. The plurality at least includes a first state register for a first unordered pair of requesting devices, a second state register for a second unordered pair of requesting devices, and a third state register for a third unordered pair of requesting devices.
