Optimizing resource-constrained C/C++ applications on embedded Linux requires profiling CPU cycles using perf and applying Link-Time Optimization (-flto).

Perf Profiling & Compilation Optimization

Terminal Commandsbash
# 1. Profile CPU performance bottlenecks using Linux perf tool
sudo perf record -g ./my_embedded_app
sudo perf report
 
# 2. Compile binary with Link-Time Optimization (-flto) and size optimization (-Os)
arm-linux-gnueabihf-gcc -Os -flto -o app_opt main.c
