Achieving both low power consumption and deterministic real-time performance is a key challenge for modern embedded systems. Intel embedded platforms are widely deployed in industrial, medical, robotics, and other edge computing applications where strict timing requirements must be satisfied while maintaining energy efficiency. Traditional real-time system configurations often disable CPU frequency scaling and deep CPU idle states to minimize latency and jitter. While this approach can improve real-time responsiveness, it significantly increases power consumption and reduces battery life in power-constrained deployments.
This proposal presents practical techniques for balancing power management and real-time performance on Intel embedded platforms running Linux with the PREEMPT_RT kernel. Based on experimental evaluation, we demonstrate that modern Intel power management features can be selectively enabled and tuned to reduce energy consumption while maintaining deterministic real-time behavior. These findings offer practical guidance for deploying power-efficient real-time applications on Intel edge platforms.
