A novel mapping algorithm for three-dimensional network on chip based on quantum-behaved particle swarm optimization

摘要

Mapping of three-dimensional network on chip is a key problem in the research of three-dimensional network on chip. The quality of the mapping algorithm used directly affects the communication efficiency between IP cores and plays an important role in the optimization of power consumption and throughput of the whole chip. In this paper, basic concepts and related work of three-dimensional network on chip are introduced. Quantum-behaved particle swarm optimization algorithm is applied to the mapping problem of three-dimensional network on chip for the first time. Simulation results show that the mapping algorithm based on quantum-behaved particle swarm algorithm has faster convergence speed with much better optimization performance compared with the mapping algorithm based on particle swarm algorithm. It also can effectively reduce the power consumption of mapping of three-dimensional network on chip.
