Embedded Systems Design
When we look around the world we live in, we find many man-made machines running round-the-clock. Have you ever wondered what makes them run continuously? What is the unique system inside these machines that make these devices so user-friendly and reliable? Sometimes we refer these devices as embedded systems? What is that embedded in these devices? In this chapter, we try to address such common doubts that arise in anyone who is newly subjected to these systems and terms.
Embedded systems:
In this section, we discuss what an embedded system is all about.Embedded systems are self-contained control systems or computer systems designed for particular purpose with bare necessary peripherals needed to run it. In the contemporary world, billions of embedded system devices including telephones, automobiles, electronic appliances and other digital devices are working around us, round the clock. It contains processor, memory, peripherals, and sensors etc.
While general purpose systems are meant for multiple purposes, embedded systems are designed for specific ones. Embedded systems may not have generic interfaces in most of the cases. Even if they have, it will have a specific purpose such as displaying output, giving input etc. Since they are used for a single purpose, the cost of implementing it will be less. Most of the time, embedded systems are time-critical applications which are not possible in general purpose systems. To learn more on embedded system design visit OpenLabPro’s tutorial guide!
