Abstract
A traditional Network-on-Chip (NoC) employs simple arbitration strategies, such as round robin or oldest first, which treat packets equally regardless of the source applications´ characteristics. This is suboptimal because packets can have different effects on system performance. We define slack as a key measure for characterizing a packet´s relative importance. Aérgia introduces new router prioritization policies that exploit interfering packets´ available slack to improve overall system performance and fairness.
