XIRAC: an optimized product-oriented near-real-time operating system with unlimited tasks and an innovative programming paradigm based on the maximum entropy method

• XIRAC integrates Shannon’s maximum entropy theorem directly into the RTOS core to regulate processor workloads, minimize context switches, and optimize process preemption. • By migrating unlimited application-layer tasks into the kernel, XIRAC significantly improves system performance, scalability, and adaptability in constrained embedded environments. • The innovative “object-emulated programming” paradigm reduces learning curves, eliminates library function and threading dependencies, and enhances developer productivity. • Real-world deployments across smart home, spectrometer, and educational platforms demonstrate optimized chip utilization, increased product competitiveness, and operational robustness.
