MIMO-OFDM SYSTEM FOR ROBUST AND EFFICIENT NEUROMORPHIC INTER-DEVICE COMMUNICATION

摘要

A Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system for inter-device communication is described. Information data from each neuromorphic chip is coded and modulated, on the basis of destination, into different channels. The parallel signals in different channels are sent serially using TDM to a central router. After signal grouping by a central switching controller, each group of signals may be delivered to corresponding transmitter in the central router for transmission to a corresponding receiver in the neuromorphic chip using TDM.

1. A system, comprising:
a plurality of neuromorphic devices, each device having a transmitter and a receiver, the neuromorphic device being configured to 1) separate a plurality of data into a plurality of parallel channels based at least in part on a destination address of the plurality of data and a frequency band; 2) combine selected data of the plurality of data that share a common frequency band, and 3) transmit the combined data; and a central router coupled to the neuromorphic device having a transmitter and a receiver and configured to 1) receive the combined data at a receiver, 2) separate the combined data into first data sharing the same destination address, and 3) transmit the first data to another one of the plurality of neuromorphic devices associated with the destination address.
