US Patent 10929322 Prioritized arbitration using fixed priority arbiter

An arbiter may include a plurality of cells, mapping logic, a fixed priority arbiter, and unmapping logic. Each cell may be associated with a corresponding client and configured to store a priority for the corresponding client. The mapping logic may be connected to the plurality of cells to order requests received from the clients according to the priorities stored in the cells. The fixed priority arbiter may receive the ordered requests and generate a grant for a winning request of the requests. The unmapping logic may use the stored priorities to yield the grant back to the winning client that sent the winning request.
