Features And Examples

<!-- TODO: each sample should have a link/path to the source code involved -->

In this chapter, you can see the complete list of features that WAMR support. And for each feature, we have an example followed demonstrating the usage of such a feature.

IWASM features

Key features

• 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 work 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 simple C APIs to embed WAMR into host environment, see how to integrate WAMR and the API list
• The mechanism to export native APIs to WASM applications, see how to register native APIs
• Multiple modules as dependencies, ref to document and sample
• Multi-thread, pthread APIs and thread management, ref to document and sample
• Linux SGX (Intel Software Guard Extension) support, ref to document
• Source debugging support, ref to document
• WAMR-IDE (Experimental) to develop WebAssembly applications with build, run and debug support, ref to document
• XIP (Execution In Place) support, ref to document
• Berkeley/Posix Socket support, ref to document and sample
• Language bindings: Go, Python

WASM post-MVP features

There are many post-MVP features for WASM. We support some of them. You can see the details in this section

• wasm-c-api
• 128-bit SIMD
• Reference Types
• Non-trapping float-to-int conversions
• Sign-extension operators, Bulk memory operations
• Multi-value, Tail-call, Shared memory
