Photo-Electronic Crossbar Switching Network for Multiprocessor Systems
Rapid progress in VLSI technologies has made it possible to implement a gigantic logic system with around 107 transistors on a single chip. For example, the multiprocessor system for multimedia applications was integrated on a single CMOS chip.1 In the system, data channels which are indispensable to communicate between processors and shared memories, was realized by crossbar switch as shown in Fig. 1. The crossbar switch has a capability to simultaneously exchange multiple data through arbitrary paths. If we design an electronic crossbar switch which operates at over 500 Mb/s, it consumes extraordinarily high power and large chip area, because it requires transmission lines and drivers. Thus on-chip interconnects become a severe limit in the operation speed and the scale of integration.
