Abstract
A hierarchical arbitration method in which requests are grouped, using a logical OR operation for example, and provided to higher levels of the hierarchy. Then, grant signals from higher levels of the hierarchy are either propagated down through each level of the hierarchy where they are used to modify, using a logical AND operation for example, grant signals. Alternatively, grant signals from all higher levels of the hierarchy may be provided to a leaf layer of the hierarchy where they are all used to modify, using a logical AND operation for example, grant signals.
