摘要

我们提出了一种CMOS硅片，光学实现了两层神经网络的反向误差传播(BEP)算法[1]。该芯片在大约2x2毫米的面积上有8个单元(或“神经元”)。每个单元由作为检测器的光电晶体管、用于光调制的调制器衬垫、采样保持电路以及执行BEP算法所需的附加电路组成。

Optoelectronic Chip for the Implementation of Back Error Propagation

We present a CMOS silicon chip that optically implements the back error propagation (BEP) algorithm [1] of a two layer neural network. The chip has eight units (or "neurons") on a area of approximately 2x2 mm. Each unit consists of a phototransistor as the detector, a modulator pad for light modulation, sample-and-hold circuits, and additional circuits necessary to perform the BEP algorithm.
