Energy and performance-aware mapping for real-timecomplex system based on NoC platform
面向实时复杂系统的基于片上网络多核平台的映射技术研究

This paper proposed a new network on chip NoC mapping algorithm which considered system energy consumption and response time to meet the real-time requirements of communication and signal processing system. It proposed an optimized energy model, which contained both energy of interconnection network and energy of processing elements and adopted a multiple-to-multiple mapping scheme. Under the bandwidth constrains and several characteristic constraints of complex communication system, such as iteration bound and injection rate, this model optimized energy consumption and response time simultaneously. The simulation results prove that the proposed mapping algorithm can achieve about 15% energy consumption savings, and has smaller response time than random mapping.
