Avx-512

A peer‑reviewed AVX‑512 SIMD algorithm dramatically accelerates integer-to-decimal string conversion, delivering up to ~1.4 GB/s throughput and 2–4x speedups over std::to_chars, with a dual‑variant (homogeneous and heterogeneous) design plus a lightweight dynamic selector that minimizes overhead across varied datasets.

A data-rich historical analysis of x86 SIMD from MMX to AVX-512, emphasizing the engineering tradeoffs, competitive dynamics, and the resulting fragmentation and partial unification efforts that shape today’s vector landscape.
