- Free Intrinsics Highlighting
Basic syntax highlighting for Intel SSE4.2 intrinsics. - Smart Intrinsics Highlighting
Easily read and navigate SIMD intrinsics with syntax highlighting tailored to each architecture.
- Standard Architectures
- Standard (requires SIMD.ai paid plan): Intel SSE4.2, AVX2, AVX512,Arm NEON,Power VSX,Power IBM-Z
- Visual Studio Code (latest stable version recommended)
- SIMD.ai account for premium architectures
This extension contributes the following settings:
code.simd.info.apiToken: Your simd.info API token. Get it from https://simd.info/.
- Users may need to reload VS Code after setting the token to enable syntax highlighting.
We are actively working to address this issue in an upcoming release.
- Some architectures (e.g. RVV 1.0,LOONGSON LSX/LASX, MIPS/MSA,Intel AMX, ARM SME2, ARM SVE/SVE2 ) are still in development.
