NeuronFlow: A Hybrid Neuromorphic – Dataflow Processor Architecture for AI Workloads

摘要

We present a novel computing architecture which combines the event-based and compute-in-network principles of neuromorphic computing with a traditional dataflow architecture. The result is a fine-grained dynamic dataflow system which avoids the coding issues intrinsic to spiking systems, and is suitable for both procedural workload and deep neural network (DNN) inference. The architecture is particularly suitable for computation of sparse CNNs and low-latency applications. We present results from GrAIOne, the first chip designed using the NeuronFlow architecture, which has 200 704 neurons implemented in a 28nm HPC + process.
