The network-on-chip (NoC) design methodology is an important trend for large system-on-chip designs to reduce the bandwidth and power constraints in traditional synchronous bus architectures. In the design of packet-based NoC, the packet-length plays an important role in the NoC throughput, latency, and energy consumption. The appropriate NoC packet-length was selected based on simulation and analysis of the packet-length effect on NoC for variable average data block length (ADBL) configuration parameters. A trade-off curve among throughput, latency, and energy consumption was developed and shows that the optimum packet length increases as the ADBL increases.
