Description-en: CPU INFOrmation library (header file)
cpuinfo is a library to detect essential for performance optimization
information about host CPU.
.
Features
.
- **Cross-platform** availability:
- Linux, Windows, macOS, Android, and iOS operating systems
- x86, x86-64, ARM, and ARM64 architectures
- Modern **C/C++ interface**
- Thread-safe
- No memory allocation after initialization
- No exceptions thrown
- Detection of **supported instruction sets**, up to AVX512 (x86) and
ARMv8.3 extensions
- Detection of SoC and core information:
