Researchers have developed the first implementation of a 3D Gaussian renderer specifically for an Intelligence Processing Unit (IPU), a type of AI accelerator. This system utilizes 1,472 independent tiles with on-chip SRAM, approximating the constraints of efficient sensor-processor architectures. The renderer routes Gaussian primitives across a NEWS grid to destination tiles and processes them using the IPU's Bulk Synchronous Parallel model, enabling local data transfer between cores to exploit spatial and temporal locality. The study analyzes bottlenecks such as inter-tile bandwidth and SRAM capacity, suggesting implications for future DRAM-free and on-sensor architectures, and potentially offering insights for optimizing conventional GPUs.
