Software Development Practices

Software development practices for embedded systems encompass the methodologies, patterns, and techniques that enable teams to create reliable, maintainable, and efficient embedded software. Unlike general-purpose software development, embedded software must address unique challenges including real-time constraints, resource limitations, hardware dependencies, and often safety-critical requirements.

Effective embedded software development requires disciplined approaches to architecture, code organization, testing, and quality assurance. The practices in this category help engineers structure their development efforts to produce software that meets demanding requirements while remaining maintainable over the long operational lifetimes typical of embedded systems.
