1. Modularity: Break down the system into smaller, manageable modules to simplify design, testing, and maintenance.
2. Scalability: Design the system to be scalable, allowing for easy upgrades and modifications.
3. Predictable timing: Ensure that the system's timing behavior is predictable and reliable.
4. Fault tolerance: Implement fault-tolerant mechanisms to ensure system reliability and availability.
5. Low power consumption: Optimize the system for low power consumption to minimize energy usage and heat dissipation.

Determinism: The most critical principle; the system must produce predictable outputs within a fixed timeframe for every input. Modularity : Break down the system into smaller,

These systems are generally categorized into three distinct types: Hard Real-Time, Soft Real-Time, and Firm Real-Time. Hard real-time systems are the most unforgiving; missing a deadline constitutes a total system failure. Examples include airbag deployment systems, where a delay of milliseconds renders the system useless. Soft real-time systems, such as streaming video applications, aim to meet deadlines but can tolerate occasional misses with a degradation in quality. Between them lies firm real-time, where missing a deadline results in an unusable result but does not cause system failure. The engineering principles discussed herein focus heavily on the challenges inherent in hard real-time design, where reliability and determinism are paramount. Determinism: The most critical principle; the system must
