About:
libcpucycles is a highly optimized microlibrary for accurately measuring CPU cycle counts on various processor architectures. It provides a simple, low-overhead interface for performance-critical applications, abstracting away hardware-specific details. Its main value is enabling precise microbenchmarking and performance analysis in C/C++ projects.

Key Features:

Low-overhead cycle counting
Supports multiple architectures (x86, ARM, etc.)
Simple C API
High precision for microbenchmarks

Use Cases:

Performance profiling of tight loops
Cryptographic library benchmarking
Real-time system latency measurement

Alternatives:

Google Benchmark – Full-featured benchmarking framework vs. lightweight cycle counter
RDTSC (inline assembly) – Manual hardware access vs. portable abstraction
