Access to the table can follow two arbitration methods.
- The first is to always prioritize table updates before lookups. In this method, the updates will always be allowed and the lookups will be stalled until there is no update.
- If the table is being updated frequently, there is a second method that performs round robin between the accesses. This will alternate between the two access types if both are pending, and give a balanced bandwidth to each. If only one is pending then it is given access regardless of the round robin state.
