Appendix C. Complete WAMR Guide
WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:
- VMcore: A set of runtime libraries for loading and running Wasm modules. It supports several execution modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). The WAMR supports two JIT tiers - Fast JIT, LLVM JIT, and dynamic tier-up from Fast JIT to LLVM JIT.
- Useful components and tools for building real solutions with WAMR vmcore:
- Full compliant to the W3C Wasm MVP
- Small runtime binary size (~85K for interpreter and ~50K for AOT) and low memory usage
- Near to native speed by AOT and JIT
- Self-implemented AOT module loader to enable AOT working on Linux, Windows, MacOS, Android, SGX and MCU systems
- Choices of Wasm application libc support: the built-in libc subset for the embedded environment or WASI for the standard libc
The WAMR VMcore supports the following architectures:
- X86-64, X86-32
- ARM, THUMB (ARMV7 Cortex-M7 and Cortex-A15 are tested)
- AArch64 (Cortex-A57 and Cortex-A53 are tested)
- RISCV64, RISCV32 (RISC-V LP64 and RISC-V LP64D are tested)
- XTENSA, MIPS, ARC
The following platforms are supported, click each link below for how to build iwasm on that platform. Refer to WAMR porting guide for how to port WAMR to a new platform.
- Benchmarks: checkout these links for how to run the benchmarks: PolyBench, CoreMark, Sightglass, JetStream2
