Abstract
A biased arbitration technique utilizes a transpose table to arbitrate access to a shared resource. Each column of transpose table is a binary bias vector encoding a bias value assigned to one of the requestors. The rows of the table are fetched to assure that requestors having high bias values are granted more frequent access to the shared resource. A look-ahead feature skips rows having all zeros and an unbiased cycle that assures all requesting ports are serviced regardless of their bias values.
