p-Circuits: Neither Digital nor Analog

📋 论文概要

本文提出了一种既非数字也非模拟的新型电路范式——p-Circuits。其输入输出接口与数字电路兼容，无需ADC/DAC，但输出不再是布尔函数，而是由输入模拟函数决定的随机二进制变量，旨在实现超高效率。

💡 主要创新点

• 提出p-Circuits新范式，打破传统数字/模拟二元划分，输入输出为数字形式但内部进行概率计算。
• 无需ADC/DAC，直接利用二进制输出的概率编码模拟信息，实现高效信息处理。

circuits aim to solve important problems with ultra-high efficiency, making use of analog and digital circuits, with well-known trade-offs. This work is about a new paradigm which is neither analog nor digital, we call it a p-circuit [See for example, 1-12]. In terms of inputs and outputs, our p-circuits look like digital circuits (Fig. 12.2.1), thus requiring no ADC’s or DAC’s. However, the output is not a Boolean function of the inputs. It is a random binary variable whose probability P(B=1) of being 1 is given by an analog function A of the inputs which takes on values continuously between 0 and 1. Building p-circuits: Figure 12.2.2 shows how a p-circuit can be built using building blocks each of which takes four inputs, combines them to compute an analog quantity
