We propose an optoelectronic parallel-matching architecture ͑PMA͒ that provides powerful processing capabilities in global processing compared with conventional parallel-computing architectures. The PMA is composed of a global processor called a parallel-matching ͑PM͒ module and multiple processing elements ͑PE's͒. The PM module is implemented by a large-fan-out free-space optical interconnection and a PM smart-pixel array ͑PM-SPA͒. In the proposed architecture, by means of the PM module each

Theoretical evaluation of the performance shows that the proposed PMA provides tremendous improvement in global processing. A prototype demonstrator of the PM module is constructed on the basis of state-of-the-art optoelectronic devices and a diffractive optical element. The prototype is assumed for use in a multiple-processor system composed of 4 ϫ 4 PE's that are completely connected through bit-serial optical communication channels. The PM-SPA is emulated by a complex programmable device and a complementary metal-oxide semiconductor photodetector array. On the prototype demonstrator the fundamental operations of the PM module were verified at 15 MHz.
