In view of the high energy consumption and latency problem due to multi-hop wired links between distant cores of traditional large-scale Network-on-Chip, a virtual torus-based adaptive wireless NoC architecture has been proposed when analyzing the existing several wireless NoC architectures. By not only adopting the automatic detection and dynamic bandwidth allocation mechanism to hot wireless link based on the sensing parameter for improved congestion measurement, but also designing the Dynamic Allocation Control Circuit Module (DACCM) for transmitter, the intra-chip topology and link bandwidth could be adaptively adjusted as different traffic patterns. Experimental results show that the proposed architecture has more significant latency improvement and energy saving under different traffic patterns or real application such benchmark as FFT.
