摘要：Photonic network-on-chip (PNoC) has emerged as a feasible solution for new multi core processor systems to avoid the limitations of power and bandwidth density of traditional electrical networks. However, it is inevitable that the photonic devices have high sensitivity to the temperature such as microring resonator which is widely used on NoCs. As the temperature is increased or decreased, wavelength shift is generated. In order to resolve that problem, an off-line task mapping based on the microring thermal perception is proposed in this paper. This scheme maps the tasks having high power consumption to the peripheral core before the application is executed, while the low power tasks are mapped first to the core of the light node that significantly decrease temperature of the optical node. The simulation results show that in a group of practical applications compared with the method based on shortest path mapping and our proposed scheme in 8×8×2 three-dimensional mesh optical NoC, later mapping algorithm significantly reduce temperature of the optical node from 1K to 2K. © 2018 Newswood Limited.
