日本三菱电气公司已生产出世界上第一个实验性动态光学神经芯片,这种芯片可使神经计算机的学习速度提高到每秒6亿个计算单位(600M CUPS)。在模仿神经元的芯片中达到的这一学习速度是世界上最快的学习速度。为了创造这一纪录,三菱公司开发出了一种实现可变灵敏度光敏二极管集成化的多重阵列技术。(可变灵敏度光敏二极管在把光转变成电时,其转换效率(即灵敏度)可以有很大的变化。) 神经计算机的特征是具有学习功能(也就是靠自己获取知识的能力)以及较灵活的信息处理功能。为了实现神经计算机的大规模生产,必须开发一种具有极高的学习速度的微型专用芯片,即所谓神经芯片。
Japan’s Mitsubishi Electric Corporation has produced the world’s first experimental dynamic optical neuro-micro-chip, which will increase the learning speed of neuro-computers to 600 million units per second (600M CUPS). This learning rate, which is achieved in a chip that mimics neurons, is the fastest learning speed in the world. To create this record, Mitsubishi developed a multi-array technology that integrates variable sensitivity photodiodes. (Variable Sensitivity Photodiodes can have a large variation in conversion efficiency (ie, sensitivity) when converting light into electricity.) Neural computers are characterized by learning (that is, their ability to acquire knowledge) and more flexible Information processing functions. In order to realize the mass production of neural computers, it is necessary to develop a micro-dedicated chip with a very high learning speed, a so-called neural chip.
