SIMD Everywhere
A header-only library providing portable implementations of SIMD intrinsics for hardware without native support.
What is SIMD Everywhere?
SIMDe is a header-only library that provides portable implementations of SIMD (Single Instruction, Multiple Data) intrinsics for systems lacking native support. It solves the problem of writing architecture-specific SIMD code by allowing developers to use intrinsics like SSE or AVX on non-x86 hardware such as ARM, enabling cross-platform performance optimization without rewriting.
Developers and engineers working on performance-critical applications who need to write SIMD-accelerated code that runs across multiple CPU architectures, such as x86, ARM, and WebAssembly.
SIMDe uniquely offers full-featured emulation of SIMD instruction sets with zero overhead when native support exists, unlike abstraction layers that limit functionality. It supports gradual porting and extensive compiler optimization hooks, making it the most flexible solution for cross-platform SIMD development.
Overview
Implementations of SIMD instruction sets for systems which don't natively support them.
