Abstract

A method of arbitration among a plurality of n units which seek access to a resource is regulated according to grants identified by means of an arbitration method, which compares between one another the priorities, generating, for each pair of the units comprising in general a unit x and a unit y with respective priorities Px and Py, a selection signal at a high level if the result of the operation Px>=Py is true. The method generates, for the pairs of the units, respective cross-request signals and generates the grant for the ith unit as a logical product of all the cross-request signals req_i_z with z ranging from 1 to n, excluding the case of z=i.
