Parallel and Fault-Tolerant Routing in Nanoscale Spin-Wave Architectures

In this paper, we present a number of parallel and fault-tolerant routing schemes for a set of nanoscale spin-wave architectures. The architectures considered here have several features, including the ability to simultaneously transmit multiple data on the same spin-wave bus using different frequencies, as well as the capability to perform concurrent writes. These parallel features result in several parallel and fault-tolerant routing schemes that are investigated here. By alternating paths to transmit data, the spin-wave architectures can be reconfigured to avoid various faults present in the underlying switches, hence rendering a set of fault-tolerant architectures.
