Platform Support

XiaoXuan Lang and XiaoYu OS are newly designed software that have good support for various mainstream platforms. At the same time, because XiaoXuan Lang has its own IR add assembly language and does not rely on traditional compilation tools and shared libraries, such as GCC and LLVM. it has faster support for newer platforms such as RISC-V and LoongArch.

XiaoXuan Lang and XiaoYu OS hope to become the preferred programming language and operating system for new platforms.

The following are tables of the support status of XiaoXuan Lang, XiaoYu OS and other software for various platforms.

XiaoXuan Programming Language

Desktop and Server

XiaoXuan Core (and XiaoXuan Managed)

The runtime includes a compiler and a virtual machine. Applications are compiled into bytecode and then run in the virtual machine. Therefore, applications are almost unaffected by the host platform. The XiaoXuan Core runtime itself is developed in Rust, so it supports most platforms.

XiaoXuan Native

It is a compiled languaged. The compiler itself is developed in Rust, so it also supports most platforms. However, the compilation target (i.e., native binary code) is determined by the compiler’s capabilities. Currently, XiaoXuan Native’s compilation targets cover most platforms, but the code generator for LoongArch64 is still under development.

Browser

XiaoXuan Script

It consists of a compiler, a standard library, and a piece of JavaScript glue code. The compiler and standard library are distributed in WebAssembly binary format. Applications are compiled by the compiler to WebAssembly binary and then run by the browser. In summary, as long as the browser supports JavaScript and WebAssembly, XiaoXuan Script and applications can be run.

Embed/IoT

XiaoXuan Micro

It includes a compiler and a virtual machine. Applications will be compiled into bytecode and merged with the virtual machine in the form of a payload. Then they will be burned into the MCU’s Flash and run. Currently, the XiaoXuan Micro virtual machine supports ARM M series architechture, such as the common Cortex-M0/M0+/M1/M3/M4/M7/M23/M33 cores. It also supports the RISC-V 32 architecture.

XiaoYu Operating System

XiaoYu OS

XiaoYu OS is based on the Linux kernel. Its userspace programs are mainly developed by XiaoXuan Core, XiaoXuan Native and Rust, so its platform support is limited by various software. However, for mainstream platforms, it can basically be well supported.

XiaoYu Micro OS

XiaoYu Micro OS is a micro operating system that adds modules such as file system, hardware abstraction layer, and serial port communication on the basis of XiaoXuan Micro. Therefore, its platform support is the same as XiaoXuan Micro. Of course, you need to download the corresponding ported version for different chips (and boards). The specific chip list can be found in the project’s documentation.
