The following article provides an outline for What is Embedded Systems? By Wikipedia, “An embedded system on a plug-in card with a processor, memory, power supply, and external interfaces. It is a microcontroller or microprocessor-based system which is designed to perform a specific task in a better way.

• The application of MOS LSI chips to computing was the basis for the first microprocessors, as engineers began recognizing that a complete computer processor system could be contained on several MOS LSI chips.
• It must be of a size to fit on a single chip, must perform fast enough to process data in real time and consume minimum power to extend battery life.
• For example, a user may want to change the volume settings on a speaker system.
• It was developed by Federico Faggin, using his silicon-gate MOS technology, along with Intel engineers Marcian Hoff and Stan Mazor, and Busicom engineer Masatoshi Shima.

Miniature wireless devices called motes are networked wireless sensors. These motes are completely self-contained and will typically run off a battery source for years before the batteries need to be changed or charged. Embedded system applications range from digital watches and microwaves to hybrid vehicles and avionics. As much as 98 percent of all microprocessors manufactured are used in embedded systems.

The 4-bit microprocessor was designed for use in calculators and small electronics, though it required eternal memory and support chips. The 8-bit Intel 8008, released in 1972, had 16 KB of memory; the Intel 8080 followed in 1974 with 64 KB of memory. The 8080’s successor, the x86 series, was released in 1978 and is still largely in use today. In 1965, Autonetics, now a part of Boeing, developed the D-17B, the computer used in the Minuteman I missile guidance system.

This encapsulation keeps faults from propagating from one subsystem to another, thereby improving reliability. This may also allow a subsystem to be automatically shut down and restarted on fault what is an embedded system detection. Unless restricted to external debugging, the programmer can typically load and run software through the tools, view the code running in the processor, and start or stop its operation.

History of embedded systems

Technically, there is some overlap between mobile embedded systems, standalone embedded systems, and network embedded systems. An embedded system is basically a connection between software and hardware. It is installed in almost all the technologies that surround you.

Embedded systems use the communication ports to transmit data between the processor and peripheral devices — often, other embedded systems — using a communication protocol. The processor interprets this data with the help of minimal software stored on the memory. The software is usually highly specific to the function that the embedded system serves. So, instead of a full-featured CPU, it may only have an 8-bit microcontroller or an application-specific integrated circuit chip or a dedicated digital signal processor . Assembly languages are often used too, especially in booting and interrupt handling.

Diagram illustrating the basic structure and flow of information in embedded systems. Printer device is considered as embedded system because it is a combination of software and hardware. Laptop is designed to perform as general purpose, therefore it will not be considered as embedded system for various reasons. ATM is an embedded system because it contains a microcontroller to control both input and output operations.

Characteristics of an Embedded System

… Smart TVs require a computer chip to handle all of the features that make it Smart, which is why it’s important to consider this. The better the processor the quicker your apps, games and features are ready to watch on the telly. Computer hardware includes the physical parts of a computer, such as the case, central processing unit , monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. Main objective of using embedded system is to handle a certain function along with a device. They are mostly developed to execute this function repeatedly and can be managed entire operating system.

Embedded systems also play vital role in the telecom industry because they help to increase ultra speed networking capabilities. In the medical industry, to use the embedded system in various medical equipments such as sensors and environment control mechanisms. In Digital Camera, all images are saved and to get process in the form of digital data in bits form. How does work it- Firstly you have to swipe your ATM card in ATM machine then insert your password, and you get your cash.

However, the final cost depends on many factors, especially when you want to get a complex solution. Embedded system programming is a complicated task that requires knowledge of certain programming languages and tech stacks. You would usually encounter C, C++, Java, and Python, although many other languages are acceptable as well. Each of these technologies wouldn’t exist without embedded software. Automation is one of the core requirements for the industrial area.

It was developed by Federico Faggin, using his silicon-gate MOS technology, along with Intel engineers Marcian Hoff and Stan Mazor, and Busicom engineer Masatoshi Shima. The first modern, real-time embedded computing system was the Apollo Guidance Computer, developed in the 1960s by Dr. Charles Stark Draper at the Massachusetts Institute of Technology for the Apollo Program. The Apollo Guidance Computer was designed to collect data automatically and provide mission-critical calculations for the Apollo Command Module and Lunar Module. Charles Stark Draper developed an integrated circuit in 1961 to reduce the size and weight of the Apollo Guidance Computer, the digital system installed on the Apollo Command Module and Lunar Module. The first computer to use ICs, it helped astronauts collect real-time flight data.

Advantages and drawbacks of embedded devices

The performance and accuracy of an embedded system is the main feature. In 95% Embedded projects, GUI is available in either hardware(LCD, GLCD, TF etc.) or software form. These units could be of any nature i.e. if you are working on an electronics system then these units will be electronic components.

After reading this post, you will be getting fully educated about What is embedded System with ease. Before going to the overview of Embedded System, Let’s first know the two basic things i.e embedded and system, and what actually do they mean. Knowledge of hexadecimal, binary, decimal, octal numbers with internal memory organization. So selection of Microcontroller or Microprocessor plays an important role here.

Why Should we use Embedded Systems?

In many instances, however, programmers need tools that attach a separate debugging system to the target system via a serial or other port. In this scenario, the programmer can see the source code on the screen of a general-purpose computer, just as would be the case in the debugging of software on a desktop computer. A separate, frequently used approach is to run software on a PC that emulates the physical chip in software. This is essentially making it possible to debug the performance of the software as if it were running on an actual physical chip. Very large-scale integration, or VLSI, is a term that describes the complexity of an integrated circuit . ULSI, or ultra-large-scale integration, refers to placing millions of transistors on a chip.

… For this reason, onboard and passive cooling fans are now mostly used for desktop computing and embedded systems in environmentally controlled areas. Now these days, modern cars contain different types of embedded system, which are performed various tasks based on their applications in your car. Arduino is an open-source IDE that aids in developing programs for Arduino microcontrollers. It includes several features and libraries that make embedded programmers’ lives easier by providing easy access. The first and foremost thing is the embedded software that decides to function of the embedded system. Embedded C language is most frequently used to program the microcontroller.

User-mode processes implement major functions such as file systems, network interfaces, etc. Many ICs in embedded systems are VLSIs, and the use of the VLSI acronym has largely fallen out of favor. Cooperative multitasking is essentially a simple control loop located in an application programming interface .

Here, we will spread light on the few real life applications of embedded systems. This type of embedded system is getting to fastest grow, due to their better flexibility. Embedded system is made with electronics parts, and on this electronic system, to install the predefined softwares then it has to capable to perform single or multiple tasks according to the application. The application layer is typically written in high-level languages such as Java, C++, and C# and includes a sophisticated user interface. In response to a user action or an event, the application layer contacts the middleware API.

In addition to the core operating system, many embedded systems have additional upper-layer software components. These components consist of networking protocol stacks like CAN, TCP/IP, FTP, HTTP, and HTTPS, and also included storage capabilities like FAT and flash memory management systems. If the embedded device has audio and video capabilities, then the appropriate drivers and codecs will be present in the system.
