面积与功耗优化的NoC映射方法

Area and Power Aware in Network on Chip Mapping

随着半导体工艺的进步和SoC技术的不断完善,产生了借鉴并行计算和计算机网络设计思想的NoC概念。针对NoC的不规则2D Mesh拓扑结构,提出了综合考虑功耗与面积的最优化映射模型,提高了运行效率。并且用模拟退火算法对3个多媒体播放器实例进行了模拟。实验结果表明,不规则Mesh相对于规则Mesh的拓扑结构,面积减小了75%,功耗减小了60%。同时与其它算法相比,平均耗时减小了90%。

With the development of semiconductor technology and SoC technology, the concept of NoC, which draws on the idea of parallel computing and computer network design, comes into being. We propose an optimization mathematical model for 2D irregular Mesh topology. It is aware of area and power consumption and improves the efficiency of the mapping algorithm. And three benchmarks of video decoders are optimized by simulated annealing algorithm. The simulation results demonstrate that irregular Mesh can provide up to 75% reduction in area and up to 60% power savings. In addition, the average time-consuming of this algorithm reduces 90% compared with other algorithms.
