A 118.4GB/s multi-casting network-on-chip for real-time object recognition processor

A 118.4 GB/s multi-casting network-on-chip (MC-NoC) is developed as communication platform for a real-time object recognition processor. To support application-specific data transactions, the MC-NoC adopts the combination of hierarchical star and ring topology with the multi-casting capability. As a result, the proposed MC-NoC improves data transaction time and energy consumption by 20% and 23%, respectively, under target object recognition traffic. The 350 k gates MC-NoC, fabricated in a 0.13 mum CMOS process, consumes 48 mW at 400 MHz, 1.2 V.
