Abstract
- Road detection is widely used in driving assistance and automotive driving. However, many state-of-the-art road de-tection methods are time-consuming and memory-consuming. In this paper, we propose an FPGA-based deep learning accelerator using the binary SegNet (BSegNet) with computing-near-memory (CNM) architecture for road detection at edges. The accelerator has optimized CNM architecture with massive bit-level parallel processing elements (PEs) and pipeline for low latency of the crit-ical path. The training model size of BSegNet with binary param-eters is only 2.1MB, and the BSegNet can achieve training accu-racy over 85% on KITTI and Cityscapes datasets. The RTL-level realized FPGA-accelerator can process the road detection with an energy-efficiency of 351.7 GOPs/W and only 18.70 W on-chip power.
