“Mixed-Signal Neuromorphic Processors: Quo Vadis?”, 2019-10-14 (; similar):
This paper outlines different design options and most suitable memory devices for implementing dense vector-by-matrix multiplication operation, the key operation in neuromorphic computing.
The considered approaches are evaluated by modeling system-level performance of 55-nm 4-bit mixed-signal neuromorphic inference processor running common deep learning feedforward and recurrent neural network models.
