Heterogeneous System

This platform is a heterogeneous computing system for neural rendering (NeRF), combining a RISC-V FPGA with a custom ARM SoC to deliver high-performance support for 3D neural rendering experiments.

该平台是一套面向 神经渲染（NeRF） 的异构计算架构，结合了 RISC-V FPGA 与 ARM SoC，为 3D 神经渲染实验提供高性能的硬件基础。

In the RISC-V stage, the system integrated the HBird E203 core on FPGA, built a Verilog-based FatFS module for DDR–SD data exchange, and enhanced SPI peripherals to enable full-duplex, high-throughput communication.

在 RISC-V 阶段，平台完成了 HBird E203 内核的移植，集成了基于 Verilog 的 FatFS 文件系统以支持 DDR–SD 数据交互，并对 SPI 外设进行优化，实现了全双工高吞吐通信。

In the ARM stage, the system was equipped with a complete firmware stack from BootROM to U-Boot, achieved stable bring-up with MMU and cache initialization, and completed Linux kernel and rootfs adaptation for system validation.

在 ARM 阶段，平台实现了从 BootROM 到 U-Boot 的完整固件栈开发，支持 MMU 与缓存初始化，并完成 Linux 内核与 rootfs 的移植与验证，确保系统稳定运行。

The platform ultimately successfully powered the lab’s self-developed NeRF rendering accelerator chip, establishing a solid system foundation for efficient 3D reconstruction and rendering.

该平台最终成功驱动了实验室自研的 NeRF 渲染加速芯片，为高效三维重建与渲染提供了坚实的系统支持。
