Multicast On-chip Traffic Analysis Targeting Manycore NoC Design

摘要: The scalability of Network-on-Chip (NoC) designs has become a rising concern as we enter the many core era. Multicast support represents particular yet relevant case within this context and been focus different research efforts, mainly due to poor performance NoCs in presence increasingly important type traffic. However, most proposed schemes have evaluated using synthetic traffic or full system, which is either unrealistic costly. While models would allow better assess their performance, existing proposals do not distinguish between unicast multicast flows often are bound given number cores. In paper, trace-based characterization presented with aim provide guidelines for modeling communications settings. To end, scaling trends aspects such intensity spatiotemporal injection distribution analyzed. novelty work resides both on its scalability-oriented approach use correlation metrics evaluate potential prediction opportunities.
