Query: Adaptive Precision CNN Accelerator Using Radix-X Parallel Connected
  Memristor Crossbars   Neural processor development is reducing our reliance on remote server access
to process deep learning operations in an increasingly edge-driven world. By
employing in-memory processing, parallelization techniques, and
algorithm-hardware co-design, memristor crossbar arrays are known to
efficiently compute large scale matrix-vector multiplications. However,
state-of-the-art implementations of negative weights require duplicative column
wires, and high precision weights using single-bit memristors further
distributes computations. These constraints dramatically increase chip area and
resistive losses, which lead to increased power consumption and reduced
accuracy. In this paper, we develop an adaptive precision method by varying the
number of memristors at each crosspoint. We also present a weight mapping
algorithm designed for implementation on our crossbar array. This novel
algorithm-hardware solution is described as the radix-X Convolutional Neural
Network Crossbar Array, and demonstrate how to efficiently represent negative
weights using a single column line, rather than double the number of additional
columns. Using both simulation and experimental results, we verify that our
radix-5 CNN array achieves a validation accuracy of 90.5% on the CIFAR-10
dataset, a 4.5% improvement over binarized neural networks whilst
simultaneously reducing crossbar area by 46% over conventional arrays by
removing the need for duplicate columns to represent signed weights.
