In today’s rapidly evolving technological era, embedded systems are ubiquitous, from small IoT devices to complex industrial control systems, the application scenarios of embedded technology are becoming increasingly widespread. However, the development of embedded systems faces many challenges: limited resources, high real-time requirements, and increasing system complexity. To cope with these challenges, design patterns, as a proven solution, are widely applied in the development of embedded systems.

In this article, we will delve into embedded system design patterns, helping developers better understand and apply these patterns to build more efficient and reliable embedded applications.

Why Focus on Design Patterns?

Design patterns are validated, general solutions for common problems in software design. They provide a standardized way to handle complexity in design, making code more modular, reusable, and maintainable.

In embedded systems, resources are often limited, and the system must operate under strict real-time requirements. Therefore, choosing the right design pattern is particularly important. Design patterns can help developers achieve efficient system design with limited resources while ensuring system reliability and maintainability.

Classification of Embedded System Design Patterns

Embedded system design patterns can be classified according to their application scenarios and functions. Common classifications include:

• Creational Patterns: Focus on object creation, making the system independent of how these objects are created, composed, and represented.
• Structural Patterns: Deal with the composition of classes and objects, achieving more complex functionalities through composition.
• Behavioral Patterns: Describe how classes or objects interact and how responsibilities are distributed.

Additionally, there are some patterns specific to embedded systems, such as concurrency patterns and state machine patterns, which provide more specialized solutions for the unique needs of embedded systems.
