google/XNNPACK — High-efficiency floating-point neural network inference operators for mobile, server, and Web

Description and use

Google’s XNNPACK is an open‑source library that provides highly optimized, low‑latency floating‑point neural‑network inference operators for a wide range of platforms—including mobile devices, servers, and WebAssembly runtimes. By leveraging platform‑specific SIMD instructions and cache‑aware algorithms, XNNPACK delivers efficient execution of common deep‑learning layers (convolutions, fully‑connected, pooling, activation functions, etc.) while maintaining a small binary footprint. It serves as a backend component for many machine‑learning frameworks, enabling fast inference without relying on heavyweight GPU or accelerator stacks.
