随机电路模型的低功耗计算原理
Principles of Low Dissipation Computing from a Stochastic Circuit Model
摘要：
我们介绍了一个互补逻辑门的场效应晶体管的一致性，最小的随机模型。我们从信息论的工具，这样的门的性能特征和研究之间的相互作用的准确性，速度和耗散的计算。使用一些通用的构建块，例如NOT和NAND门，我们能够对任意组合和时序逻辑电路进行建模，这些电路被模块化以实现计算任务。我们发现一般来说，可以实现高精度提供足够的能量消耗和时间来执行计算。然而，对于低能耗计算，准确性和速度以依赖于设备架构和任务的方式耦合。我们的工作弥合了低耗散数字器件的工程和随机热力学理论发展之间的差距，并提供了一个平台，研究低耗散数字器件的设计原则。
英文摘要：
We introduce a thermodynamically consistent, minimal stochastic model for complementary logic gates built with field-effect transistors. We characterize the performance of such gates with tools from information theory and study the interplay between accuracy, speed, and dissipation of computations. With a few universal building blocks, such as the NOT and NAND gates, we are able to model arbitrary combinatorial and sequential logic circuits, which are modularized to implement computing tasks. We find generically that high accuracy can be achieved provided sufficient energy consumption and time to perform the computation. However, for low-energy computing, accuracy and speed are coupled in a way that depends on the device architecture and task. Our work bridges the gap between the engineering of low dissipation digital devices and theoretical developments in stochastic thermodynamics, and provides a platform to study design principles for low dissipation digital devices.
