A fault-aware low-power-dissipation dynamic mapping algorithm based on NoC1

Abstract

By analyzing the defects of existing task mapping algorithms, this paper proposed a novel fault model based on spare core technology, and a fault-aware low power-dissipation dynamic task mapping algorithm FLDMA is designed based on NoC system fault, power dissipation and system performance. In the algorithm design, this paper presented the minimum mapping area selection method, designed the first-node optimization strategy, in the process of dynamic task mapping, a real-time aware NoC system state is proposed, the number and specific location of the spare cores are set according to the state of the fault node, the mapping scheme of the task migration is implemented in real time. Finally, a NoC simulation platform was created to evaluate the proposed task mapping algorithm, and the result shows that FLDMA algorithm has a better performance optimization, the fault can be detected in time, and the NoC system network communication performance can reach a better state.
