The explosive growth of deep learning (DL)-based artificial intelligence (AI) applications necessitates extraordinary computing capabilities that cannot be achieved using traditional CPU standalone computing. Therefore, the heavy mission-critical DL kernel computing currently relies on a heterogeneous computing (HGC) platform integrated with CPUs, GPUs, and accelerators, as well as substantial data storage elements. However, the metallic electrical interconnection in the existing manycore platform would not be sustainable for handling the massively increasing bandwidth demand of big data driven AI applications. Incorporating an optical network-on-chip (ONoC) for providing ultrahigh bandwidth, we propose a rapid topology generation and core mapping of ONoC (REGO) for energy-efficient HGC multicore architecture. The genetic algorithm (GA)-based REGO utilizes the structural characteristics of the optical router to the fitness function and thus compromises the trade-off between the required throughput, optical signal-to-noise ratio (OSNR), and total energy consumption. Furthermore, the crossover step accelerates the convergence speed by suppressing randomness in the GA, thus significantly reducing excessive running time owing to the NP-hard property. The generated ONoC through REGO demonstrates, on an average, an increase of 63.29 % and 22.80 % in throughput and a decrease of 50.24 % and 9.56 % in energy per bit, in the VGG-16 and VGG-19 compared with the conventional mesh- and torus-topology-based ONoCs, respectively.
