随着集成电路技术的发展,单个芯片上核的数目不断增加,多核将成为芯片体系架构的未来发展趋势。核间的互连成为芯片设计中的一个关键技术。传统的片上电互连在带宽、时延、能耗和可靠性等方面都面临挑战,光互连可以很好地解决这些问题。本文对现有片上光互连的集成光电子器件发展进行了综述,在此基础上研究了一个典型的多核光互连系统,对网络结构、节点组成和通信过程等逐一进行了分析。结果表明,光互连是未来多核系统的有效互连方式。 相似文献

This paper compares the optical and electrical interconnect systems by analyzing the efficiency and evaluating the total processing time, and design an experiment to demonstrate this performance promotion. With the increasing demand on large-scale parallel computing tasks, data transmission instead of data computing has become more and more important, so the rapid development of optical chip-to-chip interconnects techniques has gotten more attention. In this paper, we take fast Fourier transform (FFT) computation as an example to study whether and how the optical interconnection has influence on the computing performance, and three topology models are used to judging the transmission latency, and the relationship between the total processing time and the FFT points is also under investigation. Both results show parallel optical interconnection can bring large advantages in promoting computing performance. It is also found that the larger the transmission scale is, the more saving optical interconnection makes. 相似文献

Digital all‐optical parallel computing is an important research direction and spans conventional devices and convergent nano‐optics deployments. Optical bus‐based interconnects provide interesting aspects such as relative information communication speed‐up or slow‐down between optical signals. This aspect is harnessed in the newly proposed All‐Optical Linear Array with a Reconfigurable Pipelined Bus System (OLARPBS) model. However, the physical realization of such communication interconnects needs to be considered. This paper considers spatial layouts of processing elements along with the optical bus light paths that are necessary to realize the corresponding interconnection requirements. A metric in terms of the degree of required physical constraint is developed to characterize the variety of possible solutions. Simple algorithms that determine spatial layouts are given. It is shown that certain communication interconnection structures have associated intrinsic topologies. 相似文献

In this paper, we discuss the optical fiber interconnection technologies applied in the two types of parallel processing systems: 1) a backplane interconnection in a parallel processor array system and 2) a computing cluster network. We have set up a parallel processor array system using optical fiber to make point-to-point interconnection between processor elements and are developing a low-cost virtual parallel optical fiber interconnection link (VPOFLink) complying with peripheral component interconnect (PCI) local bus specifications for the computing cluster. VPOFLink is integrated with the popular PCI bus interface in order to make the link hold the same bandwidth as that of the PCI bus. It was fabricated as an available peripheral device that can been inserted into the bus slots of commercial computers directly and can operate under the control of PCI bus. Also in this paper, we demonstrate the optical fiber link for a ring network and the architecture of the ring network 相似文献
