Open-Source Xiangshan Nanhu Processor Experience Day
summary
Second-generation Nanhu boards boot Linux and run video playback, web browsing and even GPU-backed cloud game streaming; hardware is on GitHub with 6.4k stars and 765 forks. Nanhu has multiple versions (v1–v5) and the demo uses v2; Kumihoo v2 is slated for tape-out this year. Simulations use a make target called mu, multi-thread sims take ~20 minutes but prebuilt images are provided; a hello workload shows ~500 instructions in ~10,000 cycles and the design exposes ~30,000 performance counters. Debugging uses div test differential checking, injected-bug emulation and waveform checkpointing.
