Massively Parallel Processing System Using Optical Interconnection

具有处理单元（PE）和处理单元之间光互连的并行光电计算系统是实现高速并行处理的有效方法之一。在本研究中，我们以实验性的电子线路与光互连方式，利用我们原有的处理器来建构高速大规模平行处理系统，并在此系统上实现一些有意义的运算，为了实际建构此系统，我们整理了各种基本技术所需的规格，并决定了使其运作的演算法。并对每一种基本技术的性能进行了重新检验，为今后的改进提供了基础数据。实际上，我们用大规模集成电路制作了16 × 16的PE阵列，并提出了相应的算法，对计算全息图（CGH）的实际性能进行了测试，得到了有待改进的基础数据，特别是对光学器件进行了详细的说明（发射探测器阵列、光电探测器阵列、空间光调制器（SLM）、高分辨率显示器等）来满足我们的要求。在对处理元件和算法的研究中，着重分析了考虑光互连的算法，通过改变包含SLM的光学器件的波长，使之与作为发射元件的面发射激光二极管阵列（VCSEL）的波长相对应，但是我们得到了很好的实验结果。

To realize high speed parallel processing, parallel optoelectronic computing system which has processing element (PE) and optical interconnection between PEs is one of effective methodologies. In this research we construct high speed massively parallel processing system with our original PE by electronic circuit and optical interconnection experimentally, and realize some meaningful operations by the system.To construct the system actually, we arranged the needed specification for each elementally tchnology, and decided the algorithms to make it work. And we reexamined the performance of each elementally technology, and obtained the fundamental data for the improvement. Therefore the limitation in present technology and the predictin of the performance in future are explicit.In fact, we made 16*16 PE array using LSI,and developed the alorithms to execute on it. Measuring the actual performance of computer generated hologram (CGH), we obtained the fundamental data to improve.Especially we specified optical devices (emitting detector array, photo detector array, spatial light modulator (SLM), high resolution display, et.al.) to satisfy our request. As a result we found the writing time to liquid crystal spatial light modulator is the neck of system.Developing the processing element and the algorithms, we paid attention to the analysis of the algorithms which consider optical interconnection.In order to correspond to the wavelength of the surface emitting laser diode array (VCSEL) using as emitting elements, we changed the wavelength of optical device contains SLM,However we obtained good experimental results.
