通过将信息编码为数字信号传播延迟，而不是传统的逻辑电平，一些基本处理操作变得非常节能，易于实现。然后，可以通过注入信号之间的相对定时差来观察这种计算的结果。我们使用电流匮乏的逆变器作为延迟元件来演示这种方法的实施，并描述了电路级变化的应用级伪影。具体地说，我们选择了研究得很好的DNA序列比对问题进行比较，我们表明，对于合成设计，与以前的方法相比，异步竞赛的能量效率提高了10倍，密度提高了4倍。
By encoding information as digital signal propagation delay, rather than conventional logic levels, some basic processing operations become exceedingly energy efficient to implement. The result of such a computation can then be observed by relative timing differences between injected signals. We demonstrate the embodiment of such an approach utilizing current starved inverters as delay elements and characterize application-level artifacts of circuit-level variance. Specifically we chose the well-studied DNA sequence alignment problem for comparison and we show that, for the synthesized design, asynchronous races are 10x more energy efficient and 4x denser at comparable speeds as compared to prior approaches.
