GitHub - gwsystems/aWsm: WebAssembly ahead-of-time compiler and runtime. Focuses on generating fast code, simplicity, and portability.
aWsm is a compiler and runtime for compiling WebAssembly (Wasm) code into llvm bytecode, then into sandboxed binaries you can run on various platforms. It focuses on generating very fast code (best of breed for WebAssembly), having a simple and extensible code-base, and on portability. What is WebAssembly? Wasm is a standard binary format that is platform agnostic, debuggable, fast, and safe. Plea
TensorFlow Lite for Microcontrollers
TensorFlow Lite for Microcontrollers is designed to run machine learning models on microcontrollers and other devices with only a few kilobytes of memory. The core runtime just fits in 16 KB on an Arm Cortex M3 and can run many basic models. It doesn't require operating system support, any standard C or C++ libraries, or dynamic memory allocation. Why microcontrollers are important Microcontroller
