Embedded systems – Things you need to know

Embedded systems have played a significant role in people’s lives, although they were formulated to operate with no or less human intervention. Because of various factors such as small size, low cost, and simple formulation, they are prevalent.

These embedded systems play a significant role in various appliances,  instrumentation, equipment, and other home devices, and this trend may continue in the coming time. Moreover, various embedded systems courses in Delhi have been started to meet market demand.

What is Embedded Engineering?

Embedded engineering is utilizing software engineering to control machines and appliances that are not traditional systems or computers. The embedded systems are developed by integrating software engineering and non-computer appliances.

What is an embedded system? 

The combination of software and hardware formulated to perform a specific work is known as an embedded system. Embedded systems also function in massive systems. The systems can have fixed or programmable functionality. Some possible locations for embedded systems are mobile devices, Industrial machines, vending machines and toys, consumer electronics, airplanes, agricultural and processing industry devices, household appliances, automobiles, digital watches, cameras, medical Equipment, and many others.

As embedded systems are deemed computing systems, they may be either no user interface, like on appliances designed to do a single work, or complex graphical user interfaces,  like on mobile devices. Moreover, user interfaces encompass LEDs, touchscreen sensing, and buttons, even though few systems utilise remote user interfaces.

Standard Features of Embedded Systems

There are many primary features of embedded systems. Some of them are as under:

  • Embedded systems are highly task specific. They do the programmed tasks throughout their lives repeatedly.
  • Embedded systems are developed to finish a specific time in a given period. So, they are fast enough. If the vehicle’s braking system exceeds the allowed time,  it may cause an accident.
  • They have no user interfaces or sometimes minimal ones. After selecting a program, the washing machine will perform work independently and stop when the programmed task is completed.
  • Few embedded systems are created to respond to or detect external stimuli.  For instance, a GPS tracking system or a thermometer.
  • Embedded systems are developed to be much more efficient in meeting users’ needs. They have a compact size and make use of less power. Moreover, they have a reasonable price.
  • Users can not upgrade, change, or modify the embedded system. So, these systems should be highly stable and much more reliable. They are expected to perform tasks for a more extended period without causing any damage to a user.
  • Microcontrollers or microprocessors are utilised in the formation of embedded systems.
  • Connected peripherals are needed to attach output and input devices for embedded systems.
  • The hardware of an embedded system is used for performance and security. While its software is used to implement all the features.

Use of embedded systems in Healthcare

Embedded systems’ use in healthcare services is ubiquitous. Many diagnostic systems and wearable devices are designed to monitor patients’ overall health and obtain and assess data.

The embedded systems are present in various healthcare devices, from simple thermometers to complex MRI and ECG machines. These systems have provided ease and benefits to both patients and doctors.
