Functions and Importance of Embedded Software — Lesson 2

Basics of Embedded Systems Functions and Importance of Embedded Software — Lesson 2

The lesson discusses the benefits of embedded software, such as increased power and flexibility, reduced size and energy consumption, and improved safety and performance. An example is provided of an air conditioner adjusting airflow to reach a set temperature, illustrating a typical three-step process in embedded systems: reading the current and desired states, computing the gap, and executing commands to align the two states. Additionally, the lesson outlines the typical process of embedded system development, encompassing both hardware and software aspects, and the importance of clear, complete, and testable requirements. It emphasizes the multidisciplinary nature of system design and the need for software optimization due to hardware constraints. Safety and security are underscored as paramount concerns, especially in critical applications where failure can have catastrophic consequences. The lesson points out the high costs and challenges of developing safety-critical software and introduces Ansys SCADE® embedded software product collection as a solution for model-based development and code generation that complies with stringent industry standards while offering cost and effort savings.
