Query: SNRA: A Spintronic Neuromorphic Reconfigurable Array for In-Circuit
  Training and Evaluation of Deep Belief Networks   In this paper, a spintronic neuromorphic reconfigurable Array (SNRA) is
developed to fuse together power-efficient probabilistic and in-field
programmable deterministic computing during both training and evaluation phases
of restricted Boltzmann machines (RBMs). First, probabilistic spin logic
devices are used to develop an RBM realization which is adapted to construct
deep belief networks (DBNs) having one to three hidden layers of size 10 to 800
neurons each. Second, we design a hardware implementation for the contrastive
divergence (CD) algorithm using a four-state finite state machine capable of
unsupervised training in N+3 clocks where N denotes the number of neurons in
each RBM. The functionality of our proposed CD hardware implementation is
validated using ModelSim simulations. We synthesize the developed Verilog HDL
implementation of our proposed test/train control circuitry for various DBN
topologies where the maximal RBM dimensions yield resource utilization ranging
from 51 to 2,421 lookup tables (LUTs). Next, we leverage spin Hall effect
(SHE)-magnetic tunnel junction (MTJ) based non-volatile LUTs circuits as an
alternative for static random access memory (SRAM)-based LUTs storing the
deterministic logic configuration to form a reconfigurable fabric. Finally, we
compare the performance of our proposed SNRA with SRAM-based configurable
fabrics focusing on the area and power consumption induced by the LUTs used to
implement both CD and evaluation modes. The results obtained indicate more than
80% reduction in combined dynamic and static power dissipation, while achieving
at least 50% reduction in device count.
