Fecha de publicación: 03/02/2022 Fuente: Wipo "digitalization" A system including digital oscillators and at least one programmable interconnect is described. The programmable interconnect(s) provide weights for and selectably couples at least a portion of the digital oscillators. The digital oscillators and the programmable interconnect(s) form an optimization processing unit (OPU). A system for performing reversible logic is also described. The system includes digital oscillators coupled to perform a logic operation and an error correction unit coupled to the digital oscillators. The error correction unit is configured to sample states of the digital oscillators, detect error(s) in the states, and tune connection coefficient(s) between the oscillators in response to detecting the error(s).
