Features And Examples

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
