光频收发信机制及其在计算机中的应用

冯诺曼机器以提高处理器频率增强性能,多处理器环境当中的系统性能决定于使更多处理器协同工作。通信带宽是高性能计算系统的首要瓶颈。本文提出一种芯片间通信的神经脊,把数以百计的芯片连接成一组网络,为多处理单元并行运算提供一个骨架。用相干的激光作为通信媒介,以垂直腔面的激光元件组成收发信机。相干光充分利用谐振线路放大器的特性提升通信的扇出,令芯片间的信息传递效率大大提高。使通信网络的复杂性从按通信端点数n*(n+1)式上升,变为线性增加。

Optical Tranceiver Mechanism and Its Application in Computer

Clock speed is the main aim to increase the efficiency of a Von-Neumann machine. However, it is more important to let more CPUs work together in a multi-processor environment. Bandwidth is the bottle-net for chips communication in high performance computing. This paper supposes a high speed backbone makes use of several neural nodes stacking them together to form a helical spinal. Hundreds of chips are connected to form a group via a network formed by integration of buses. This provides a skeleton for multiprocessors to have parallel processing. Further more, laser is supposed to be the transmitting media inside the light nervous to simply the network structure form exponential to linear increase with the number of terminals.
