摘要: 根据相邻信号线的逻辑电位计算两线耦合动态功耗.将这种方法应用于计算N位总线的M个连续时刻的功耗,得到N位总线的平均功率因子,以反映N位总线的相邻耦合平均动态功率.根据程序地址总线的数据,搜索得到对应最小平均功率因子的总线内信号线的排布方式,实现最优的低功耗总线布线,使程序地址总线的动态功耗降低了38.2%.

Abstract: According to the logic value of an adjacent signal, the coupling dynamic dissipation of the adjacent signal is computed. The method is used in calculating the dynamic dissipation of the N bit bus during M, so the average dissipation factor pM is obtained to reflect the average power of the N bit bus. With the datafile of the program address bus, the best routing of the bus is searched for by computing the lowest pM. As a result, the dynamic dissipation of the bus is reduced by 38.2%.

Key words: low-power, adjacent signal, dissipation factor, routing
