Embedded System Dependability (Overview)

Embedded systems, like those in cars and airplanes, need to be reliable and safe. They make sure they’re dependable by checking a few things. Firstly, they see if the system won’t break often (reliability).

Then, they check if it can be fixed quickly if it does break (maintainability). They also see if it’s available when needed (availability). Safety is big too; they want to make sure if it breaks, it won’t cause harm. Also, they check if data is kept safe and communication is genuine (security).

Efficiency is important too. They check a few things to see how well they’re using resources. Firstly, they look at how much energy they’re using, especially for systems with batteries. They also look at how much space the code takes up. Since they can’t store much code, they keep it small.

Embedded systems also try to use as little energy and hardware as possible to do the job. Lastly, for portable systems, they make sure they’re not too heavy. Plus, they try to keep costs down, especially for things  like phones, where many are made.

So, embedded systems keep things running smoothly by being dependable and efficient. They check things like reliability, safety, and energy use to make sure they’re doing a good job.
