Embedded Systems Lecture Notes: Embedded systems is the combination of computer memory, input or output peripheral devices, and computer processor. As the name suggests, it is something that is attached to something else. It has a particular function within a longer electrical or mechanical system. It is the part of a computer frequently including electronic or electrical hardware and mechanical parts. An embedded system controls the physical activities of the machine it is embedded in. Nowadays, many devices are controlled by an embedded system. Approximately ninety-eight percent of all microprocessors have embedded systems in it. You can think of the embedded system as hardware that has software attached to it. In this article, you will get complete details about the study materials of embedded systems.

Introduction to Embedded Systems Notes

Embedded Systems is the kind of hardware of a computer system with the software as well that is designed to perform a particular function independently or as a part of a large machine. It helps in real-time operations. The complexity level of this system depends on the function it is assigned. Both small and large machines use embedded systems. Starting from digital watches to avionics, an embedded system has been found in most of the machines in recent time. If you are studying embedded systems and confused about the study materials, you may check out this article thoroughly.
