IAA03_fast_math is a single-header math kernel(Atan2 only for now) designed to eliminate the "Trigonometry Tax" in high-throughput systems (Physics Engines, Audio DSP, and ML Pre-processing). Branchless ,ILP and SIMD (AVX2/SSE4.1), it achieves up to a ~186x per-element throughput speedup over std::atan2 while being IEEE 754 compliant

A resurrection of a very old project, brought back to life to save my brain.

A optimized Game of Life generation.

Safety-hardened GEMM (matrix multiply) implementation achieving 169.8 GFLOPS on Intel i9-14900. Built for embedded systems and safety-critical applications where reliability matters as much as speed. 162× faster than naive, zero UB, fully validated.
