Abstract
Methods and apparatus are provided for implementing a bus arbitration priority encoding scheme with fairness. Bus arbitration logic is connected to multiple primary components or devices. The multiple primary components send requests to bus arbitration logic. The bus arbitration logic uses a request vector and an arbitration vector to determine a grant vector. The grant vector indicates what primary component should be allowed bus access.
