Module simd 

SIMD-accelerated operations.

Platform support:

• ARM64: NEON intrinsics
• x86_64: SSE2/AVX2 intrinsics
• Other (WASM, etc.): Scalar fallbacks

Modules:

• hex — hex encode/decode (NEON TBL, SSE2/AVX2 arithmetic, scalar LUT)
• image — nearest-neighbor RGBA downsample (NEON gather, SSE2 gather, scalar)

Modules

hex

SIMD-accelerated hex encoding and decoding
