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 advances in semiconductor technology and continuous improvement of SoC technology, a NoC concept has emerged that draws on parallel computing and computer network design ideas. Aiming at the irregular 2D Mesh topology of NoC, an optimal mapping model considering power consumption and area is proposed, which improves the operation efficiency. Simulations were performed on three multimedia player instances using the simulated annealing algorithm. The experimental results show that the area of ​​irregular Mesh is reduced by 75% and the power consumption is reduced by 60% compared with that of regular Mesh. Compared with other algorithms, the average time-consuming is reduced by 90%.
