Abstract

4D Gaussian Splatting (4DGS) has widespread applications in fields such as VR, AR and industrial simulation. However, 4DGS suffers from significant memory requirements, redundant computations and low PE utilization. This paper introduces adaptive quadratic interpolation, recursive computation reuse and tree-based parallel rendering to tackle these challenges. The processor in the paper achieves a rendering energy of$0.24 ~\text{mJ} /$frame and improves energy efficiency by$6.11 \times$on the D-Nerf dataset.
