Fast UTF-8 validation with range algorithm (NEON+SSE4+AVX2)

Fast C functions for the computing the positional popcount (pospopcnt).

Efficient C functions to compute the summary statistics (flagstats) for sequencing read sets.

LLaMeSIMD - The Ultimate SIMD Intrinsic & Function Translation Benchmarking Suite

A fresh (experimental) look at Scilab 6.x

X86-64 bilateral instruction tokenizer implemented in C. Supports the following processor extensions: AES, AVX, AVX2, AVX512, FMA, MMX, SSE, SSE2, SSE3, SSE4, x87(FPU), VMX. In order to ease testing, a diassembler which transforms tokens into compilable assembly (for NASM compiler) has been implemented.

Software for Burstcoin cryptocurrencies. Support for CPU and GPU. More information at cosburst@gmail.com

A cross platform Redis Module Example that warns and uses the optimized functions based on instruction set extensions available and or microarchitecture

Drop-in Pillow 13 with SIMD kernels: about 6x faster on x86-64 (SSE4.1, AVX2, AVX-VNNI) and 3x on arm64 (NEON). Wheels on PyPI. A fork of Pillow-SIMD.

Fix "Illegal instruction (core dumped)": opencode, Cline CLI, Bun and Antigravity CLI for old x86-64 CPUs without SSE4.2/AVX (Core 2 Duo, Pentium Dual-Core, Celeron, Athlon 64, Phenom II) on Linux

Sleef inline headers

SIMD implementations of ssea primitives (base94 codec, delta coding, XOR masking, byte permutation) for SSE2/SSSE3/SSE4.1/SSE4.2/AVX/AVX2 with CPU auto-detection and per-algorithm best-level dispatch. Output identical to scalar, byte for byte.
