Abstract

One of the key steps in Network-on-Chip (NoC) based design is spatial mapping of cores and routing of the communication between those cores. Known solutions to the mapping and routing problem first map cores onto a topology and then route communication, using separated and possibly conflicting objective functions. In this paper we present a unified single-objective algorithm, called Unified MApping, Routing and Slot allocation (UMARS). As the main contribution we show how to couple path selection, mapping of cores and TDMA time-slot allocation such that the network required to meet the constraints of the application is minimized. The time-complexity of UMARS is low and experimental results indicate a run-time only 20% higher than that of path selection alone. We apply the algorithm to an MPEG decoder System-on-Chip (SoC), reducing area by 33%, power by 35% and worst-case latency by a factor four over a traditional multi-step approach. Copyright 2005 ACM.
