SRCNN‑cpp

• SRCNN (Super Resolution Convolution Neural Network) implementation with pure C++.

• Transform convolution calculation to matrix multiplication for re‑using techniques of matrix multiplication optimization.

• Optimize matrix multiplication from scratch with 10x speedup.

sse2neon

• A translator from Intel SSE intrinsics to Arm/Aarch64 NEON implementation.

• Support obtaining hardware timestamp on Armv7‑A.

• Improve precision of reciprocal of square‑root conversion to at least 24 bits, giving more accurate result for ray tracing programs such

as Blender and Embree.

• Fix incorrect result of reciprocal of square‑root conversion when dealing with positive/negative infinity.

• Introduce fast and deterministic RNG for testing on various platform/environment.

simdjson

• Parsing gigabytes of JSON per second.

• Implement JSON indented output string functions with CRTP for best performance.
