Abstract

VoxCAD, an intelligent low-power dToF SoC for end-to-end 3D perception applications, is presented with three features: 1) LiDAR dToF sensing-integrated 2D-ROI guided point cloud construction for reducing sensor transfer energy and latency; 2) coarse-fine sector-wise voxelization with a central-computation unit for reducing on-chip memory size and EMAs; and 3) reconfigurable tri-mode eDRAM CIM macros with hybrid 1T1C/2T1C cells for supporting 3D transformers at high area efficiency and storage density.
