RISC-V Summit

Berberis is an open source userspace dynamic binary translator facilitating cross-architecture development and testing of RISC-V Android applications. It translates native riscv64 code inside of an Android APK to x86_64 at runtime, enabling developers to test RISC-V builds of their apps on their workstations when target device hardware is unavailable. This presentation will cover the motivation and benefits of userspace translation versus whole-system emulation, the challenges of translating RISC-V code to x86_64, and use cases and future directions for the project.
