Memory bandwidth has become the real-time bottleneck of current deep learning
accelerators (DLA), particularly for high definition (HD) object detection.
Under resource constraints, this paper proposes a low memory traffic DLA chip
with joint hardware and software optimization. To maximize hardware utilization
under memory bandwidth, we morph and fuse the object detection model into a
group fusion-ready model to reduce intermediate data access. This reduces the
YOLOv2's feature memory traffic from 2.9 GB/s to 0.15 GB/s. To support group
fusion, …
