Evaluation of silicon consumption for a connectionless Network-on-Chip
  We present the design and evaluation of a predictable Network-on-Chip (NoC) to interconnect processing units running multimedia applications with variable-bit-rate. The design is based on a connectionless strategy in which flits from different communication flows are interleaved in the same communication channel between routers. Each flit carries routing information used by routers to perform arbitration and scheduling of the corresponding output communication channel. Analytic comparisons show that our approach keeps average latency lower than a network based on resource reservation, when both networks are working over 80% of offered load. We also evaluate the proposed NoC on FPGA and ASIC technologies to understand the trade-off due to our approach, in terms of silicon consumption.
