Berberis: Dynamic Binary Translation from RISC-V to X86_64 on Android

on YouTube ↗17m

" summary

Berberis translates riscv64 native libraries inside Android APKs to x86_64 at runtime, running only user code while the kernel, Android runtime and system services run natively so most of the OS executes at near‑native speed. It supports RV64G plus compressed, vector and bit‑manip extensions, NDK libraries except Vulkan, and achieves >99% CTS pass rate for native tests; validated Maps, YouTube, Music and Play Store as working and performant. Translation uses an interpreter, a light translator and a heavy optimizer; vector emulation is currently slow and LR/SC atomics are software‑emulated.
