Introduction

Embedded systems are meant to work with little to no human interference. However, due to several advantages of embedded system, it has developed into a vital part of living souls. Thus, with minimum effort and many benefits, they become mainstream. Many modern gadgets, home appliances, and other devices rely heavily on these frameworks.

This blog covers the types, benefits, and disadvantages of Embedded systems. Read on to know more.

What is an Embedded System?

Before knowing the embedded systems advantages and disadvantages, let's see their definition.

It is a combination of software and hardware with either fixed capabilities or flexibility. Thus, its design can fit into a specific capacity or capacity within a larger framework. They also have many advantages of an embedded system. A common example of a set structure that can only detect smoke is an alarm.

Embedded System Characteristics

An embedded system has the following important features:

• Needs to be executed continuously.
• To interface information and produce devices, it must connect to peripherals.
• Provides high standards of reliability and strength.
• Minimal UI is necessary.
• Memory restriction, simplicity, and less force usage.
• Any additional PC memory is not necessary. This is also an embedded operating system advantages.
• It should be highly reliable and accessible.
• Built around an ongoing working framework.
• It has a simple and diskless activity, ROM boot, for the most part.
• Intended for a single clear assignment.

Types of Embedded Systems

You can classify them on the basis of:

1. Performance and Functional requirements
2. Performance of the Microcontroller

Additionally, you can see some of the other benefits of embedded system, in each category.
 

1. Performance and Functional requirements

Based on the performance and functional requirements, these systems split into four categories.

• Real-Time Embedded Systems

These systems produce results in real-time within a specific time window. Thus, they are also built and designed to carry out a given task. Moreover, it completes that task within a set amount of time.

• Stand-Alone Embedded Systems

Stand-alone Systems may operate independently. Therefore, it is also one of the advantages of embedded system in this category. Hence, they are self-sufficient and independent of a host system. Moreover, the design of standalone systems allows for the reception of an input. Furthermore, it processes that information and produces the intended output.

• Networked Embedded Systems

In these systems, network-connected networks exist to fulfil their assigned responsibilities. Thus, they are made up of interconnected components including sensors and controls.

• Mobile Embedded Systems

They are small, portable embedded systems. Furthermore, they are suitable for smaller gadgets.
 

2. Performance of the Microcontroller

Embedded Systems are divided into three categories based on their microcontroller performance. However, these categories also offer the advantages of embedded systems.

• Small Scale Embedded Systems

Small-scale embedded system design and development use an 8-bit microcontroller. Additionally, batteries are a source of power for the microcontroller.

• Medium Scale Embedded Systems

A single 16-bit or 32-bit microcontroller or a network of linked microcontrollers is there in a medium-scale system. However, many people do not prefer these systems because of their hardware and software complications.

• Sophisticated Embedded Systems

These systems operate on complex hardware and software. Moreover, they use numerous algorithms. Thus, they need a reconfigurable CPU and programmable logic array.

Examples of Embedded Systems in Daily Life

Some of the most popular examples include:

• Home security systems.
• Digital alarm clocks.
• Electronic parking metres and parking pay stations.
• Robotic vacuum cleaners 
• Smartwatches and digital wristwatches.
• Washing machines and dishwashers.
• Air-conditioners and thermostats.

List of Devices that Contain Embedded Systems

Devices that contain embedded systems include:

• Appliances like refrigerators, washing machines, and microwave ovens.
• Temperature measurement systems.
• Calculators. 
• Digital cameras.
• Digital wristwatches.
• MP3 players.

Advantages of Embedded System

The most common embedded system advantages include:

• It is simple to increase production.
• They also make the most of resources like CPUs and memory
• Moreover, they are resistant to a variety of environments.
• Error repetition is less frequent.
• To deliver a timely reaction
• It is not intuitive to use.
• Little storage for data
• Less redundant work is among the top advantages of embedded system.
• To execute pre-planned scripts and user applications
• Each item of the outcome is not as expensively priced.
• It just has a small number of connections.
• Also offers more safety
• Greater dependability
• The compact size makes it portable.
• Minimal power use is also a benefit
• Accurate outcomes with more accuracy
• Higher speed

Some Disadvantages of an Embedded System

A few limitations also apply to embedded systems, such as:

• Troubleshooting is more difficult
• The process of transferring data from one system to another is also challenging.
• Hardware has restrictions because of its use for specific purposes,
• Resources and memory are both insufficient. Therefore, it affects the use of embedded system.
• Designing an embedded system means additional development work
• Once an embedded system has been created you are not allowed to change, improve, or upgrade.
• Maintenance is also challenging.
• It is challenging to make a backup of embedded files.
• To prevent any system problems, it is necessary to reset every setting.

Conclusion

Embedded systems have grown to be an essential component of everyday life. Moreover, they are popular due to factors like affordable price, compact size, and easy design. These systems are also useful in many gadgets, instruments, and home appliances today. Additionally, this trend is anticipated to continue.
