【摘要】 提出了一种Reed-Muller(RM)逻辑电路的功耗估算方法.将多输入AND/XOR门分解成由2输入AND/XOR门构成的树,采用信号的跳变密度和信号概率来计算内部节点信号的开关活动率,从而实现电路的功耗估算.实验结果表明:该方法得到的估算结果与电路实际功耗二者之间具有良好的线性关系.更多还原

【Abstract】 A power estimation approach was proposed for Reed-Muller (RM) logic circuits. Given the signal probability and transition density of input signals, AND/XOR gates were decomposed into a number of 2-input gate tree, its switching activity was calculated to estimate the power dissipation. Experimental results indicated that the proposed approach can well predict the power dissipation for RM logic circuits without detail process information.更多还原
