未来的系统将需要不同级别的高带宽和密集的通信路径。商用高性能计算机现在开始在机柜间级别使用光学互连。这些连接通常由光纤带组成，每根光纤在200到300米的距离上以每秒1到2 Gbit的速度传输信号。总带宽高达每秒30Gbit。作者建议将合适的光电子器件与硅电子集成，这将允许设计人员使用光通信通道在芯片上和芯片外传输数据。作者描述了一种用于高速计算、图像处理和机器人视觉系统的光学互连体系结构。他们得出结论，光电并行处理系统将克服传统电子技术面临的一些互连问题--允许高速计算机具有足够强大的视觉和图像处理应用。
Tomorrow's systems will need high-bandwidth and dense communication paths at various levels. Commercial high-performance computers are now beginning to use optical interconnections at the intercabinet level. These connections usually consist of optical fiber ribbons, with each fiber carrying signals at 1 to 2 Gbits per second over distances of 200 to 300 meters. The aggregate bandwidth is as much as 30 Gbits per second.The authors propose integrating suitable optoelectronic devices with silicon electronics, which will allow designers to use optical communication channels to transfer data on and off chips. The authors describe an optically interconnected architecture for high-speed computation, image processing, and robotic vision systems.They conclude that optoelectronic parallel-processing systems will overcome some of the interconnection problems facing conventional electronic technology-allowing high-speed computers powerful enough for vision and image-processing applications.
