The wormhole adaptive recovery-based routing via pre-emption(WARRP) core optoelectronic chip, which integrates coredeadlock-handling circuitry for a fully adaptive deadlock-freemultiprocessor network router, is presented. This chip demonstratesprimarily the integration of complex deadlock-recovery circuitry andfree-space optoelectronic input–output on a monolithicGaAs-based chip. The design and implementation of thefirst-generation, bit-serial, torus-connected chip that uses 1400transistors and six light-emitting diode–photodetector pairs is presented.
