This work presents the first chip designed for low-power light-field factorization for naked-eye full-parallax 3D displays in real-time. It supports 7x7-perspective light fields and dual-layer rank-1/-2/-4 factorization with consuming 283/442/971 mW. It factorizes 22-85x faster and consumes 311-772x less power compared to GPU RTX2080 Ti platform. The DRAM bandwidth is reduced from 126.8 to 0.8 GB/s and the energy effifiency is improved by a factor of 10 thousand, which facilicates the real-time multiview 3D diaplay technology in energy-aware portable devices and consumer electronics.
