Abstract
A configurable weighted round robin arbitration mechanism adapted to receive as input a vector of order N, wherein each bit in the vector represents the eligibility of a queue or other source of data to participate in the arbitration process. A bit set to `1` in the vector indicates that the corresponding queue is eligible to participate in the arbitration process. Conversely, a bit set to `0` in the vector indicates that the corresponding queue is not eligible to participate. The arbitration process of the present invention enables a user to assign each queue (which corresponds to one of the bits in the vector) an individual weight. This results in a modified vector that represents the incoming vector after being handled by the weighting process. By giving each bit in the vector a weight, the user can control the probability of each bit, i.e., queue, being selected in the arbitration process.
