Paper Abstract

We propose an optoelectronic parallel-matching architecture (PMA) that provides powerful processing capability for distributed algorithms comparing with traditional parallel computing architectures. The PMA is composed of a parallel- matching (PM) module and multiple processing elements (PE's). The PM module is implemented by a large-fan-out free-space optical interconnection and a parallel-matching smart-pixel array (PM-SPA). In the proposed architecture, each PE can monitor the other PE's by utilizing several kinds of global processing by the PM module. The PE's can execute concurrent data matching among the others as well as inter-processor communication. Based on the state-of-the-art optoelectronic devices and a diffractive optical element, a prototype of the PM module is constructed. The prototype is assumed to be used in a multiple processor system composed of 4 X 4 processing elements, which are completely connected via 1-bit optical communication channels. On the prototype demonstrator, the fundamental operations of the PM module such as parallel-matching operations and inter- processor communication were verified at 15 MHz.
