摘要
Abstract
Aimed at the high energy consumption and communication delay due to multi-hop wired links between dis-tant cores of traditional and large-scale network-on-chip(NoC),a virtual Torus-based adaptive wireless NoC(VT-AWiNoC) structure is proposed.The automatic detection and dynamic bandwidth allocation mechanism to hot wireless link based on the sensing parameter for link congestion measurement is adopted.Moreover,the dynamic allocation circuit for transmitter is de-signed to realize adaptive adjustment of the intra-chip topology and link bandwidth as different traffic patterns.We compare the performance of our proposed VT-AWiNoC to other hybrid wireless NoC topologies by setting up the energy consumption and delay estimate models.Experimental results show that the proposed topology obtains a delay improvement of 16. 52%to 23. 27% under random traffic pattern,an energy saving per packet of 39. 19%under hotspot traffic pattern,a delay improve-ment of 17. 20%to 21. 68%and energy saving per packet of 23. 49%on real application such benchmark as FFT(Fast Fou-rier Transform).The proposed topology achieves higher performance gains with small additional area cost.关键词
