ABSTRACT:
A method for arbitrating access to a resource shared by several electronic elements. Each element is allocated a first counting value and a first penalty, the first counting value is decremented in synchronization with a clock signal, and is incremented by a value equal to the first penalty every time the element is selected for an access cycle. When several elements are simultaneously waiting to access the shared resource, an element is selected to access the resource if its first counting value is lower than or equal to a determined threshold, and is lower than the first counting values of the other elements having sent an access request.
