Run unmodified Android and Linux apps on RISC‑V.
What is ChaCha?
ChaCha is a binary translation system that lets RISC-V devices run applications that were built for other CPU architectures. It supports both Linux and Android, with no changes to the applications binaries.
Unmodified apps. Install Android apps straight from the app store, or run existing Linux programs, and they just work on RISC-V.
Performance. 77.5% translation efficiency on SPEC CPU2006, measured on SpacemiT K3.
Compatibility. 99% pass rate on Linux system-call tests.
Reference platforms. Ubuntu 26.10 and AOSP 17 on SpacemiT K3, with integration packages and documentation for porting to your own Linux or Android platform.
What do we offer?
ChaCha licenses for RISC-V SoC vendors and device makers, for commercial deployment.
Support for integration, testing, deployment, and new feature development.
