Abstract
A device includes a first and a second stage round robin arbitrations. The first stage receives request signals and selects a subset the request signals. Each request signal is associated with whether a component is requesting access to a common resource. The second stage receives the selected subset and grants access to the common resource to each request signal of the selected subset that is requesting access, in a round robin fashion. The second stage outputs an enable signal to the first stage when the selected subset is processed. The first stage selects another subset and transmits the selected another subset to the second stage for round robin processing thereof. The process is repeated until all subsets with at least one request signal to access the common resource is processed and granted access in a round robin fashion.
