Accelerating Image-Sensor-Based Deep Learning Applications

We review two inference accelerators that exploit value properties in deep neural networks: 1) Diffy that targets spatially correlated activations in computational imaging DNNs, and 2) Tactical that targets sparse neural networks using a low-overhead hardware/software weight-skipping front-end. Then we combine both into Di-Tactical to boost benefits for both scene understanding workloads and computational imaging tasks.
