Abstract

Free-space optical interconnection is an attractive technique for interprocessor communications in future multiprocessor systems. The previously developed multiprocessor system, COSINE-1 (computer systems employing optical spatial interconnections for experimentation-1), used manually reconfigured board-to-board free-space optical interconnections. This paper describes COSINE-2, an advanced version of COSINE-1. COSINE-2 employs a rearrangeable 128 × 128 free-space multichannel optical switch implemented with a polarization-multiplexing technique. The optical switch offers full flexibility for reconfiguring the processor network. A system is built and experimentally confirmed to be completely reliable. System operations including processor network reconfiguration are successfully performed.

摘要

自由空间光互连是未来多处理器系统中用于处理器间通信的一种有吸引力的技术。先前开发的多处理器系统COSINE-1（用于实验的采用光空间互连的计算机系统-1），使用手动重新配置的板对板自由空间光互连。本文介绍了COSINE-1的高级版本COSINE-2。COSINE-2采用了一种基于偏振复用技术实现的可重排128×128自由空间多通道光开关。该光开关为重新配置处理器网络提供了充分的灵活性。构建了一个系统并通过实验证实其完全可靠。包括处理器网络重新配置在内的系统操作均成功执行。
