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.
