Multi-ring-based optical network-on-chip topology structure design method

Abstract

The invention discloses a multi-ring-based optical network-on-chip topology structure design method, and is used for solving the problems of severe network congestion, low extensibility and complex network of the existing optical network-on-chip topology structure. The implementation steps are that a ring set collection G is set; the ring set collection G is initialized; whether each ring set gq in the initialized ring set collection G0 has no ring crossing is judged; the network congestion factors of all the ring sets in a target ring set collection Gn are calculated; the previous 2N ring sets of all the ring sets are selected according to ordering of the network congestion factors; the previous 2N ring sets are optimized and updated so that the target ring set collection Gn is obtained; and the updating number n is judged, and the ring set gmin of the lowest congestion probability factor is selected. The method of selecting the multi-ring topology of the lowest network congestion probability factor and the single wavelength communication method are adopted so that the congestion situation of the optical network-on-chip can be alleviated, the extensibility of the optical network-on-chip can be enhanced and the network complexity and cost can be reduced.
