Day by day, IoT and mobile devices are getting to rule our life. From car and trucks to grocery and home appliances, embedded applications are flooding globally. Embedded systems are now a ‘part and parcel’ of our lives, but there has to be a process to manage the process before they knock the floor. Understanding embedded systems programming is a must, and once you get what precisely the embedded systems are used for, it becomes easy to see what has gone into their make. Here’s everything in a short page to know all about embedded systems right from the ‘top to toe.’
What is an Embedded System?
Embedded systems are mainly designed to work for a specific function using both, computer hardware and software. It enables you to complete the tasks most straightforwardly and effectively. These are formulated to work within larger systems with zero or no human intervention. However, there’s a lot of difference between a general-purpose system and an embedded system designed to meet a single task. Embedded systems can be both; no user interface (UI) and complex graphical user interfaces (GUIs) through sensors or remote functionality. These are usually designed in such a way that it avoidshuman interventions and controls functions efficiently.
On the other side, embedded systems security enables the users to protect the software from malicious attacks. Embedded systems are designed in such a way that they are capable of preventing errors.
A few examples of embedded systems are refrigerators, washing machines, television, ATMs, automobile, medical equipment, Microwave oven, toys, cameras, etc. Although it is pretty much clear that each one of these are executed with a complex GUI for uninterrupted and error-free UI and monitoring functions.
Role of Embedded Systems in Internet of Things (IoT)
Internet of Things (IoT) is a term used to define the combination of sensors, actuators, and all the processors that involve hardware board design and development, software systems, web APIs, and protocols, which together create a connected environment of embedded systems.
How do Embedded Systems Work?
Microcontrollers play a significant role in the working of embedded systems. Apart from that, digital signal processors (DSP), field-programmable gate arrays (FPGA), GPU technology, application-specific integrated circuits (ASIC), and gate arrays also enable the embedded systems to work efficiently. The firmware is stored in a ROM or memory chip that run with limited computer hardware resources.
If we go with the steps on how embedded systems work, then:
- A user first gives the analog input through sensors, keypad, touch buttons, etc.
- Following that, the system gives out the output by processing the information and converting it into a digital one using a monitor, LCS, etc.
Types of Embedded Systems
1. Network embedded systems
Network embedded systems are dependent on the connected network to perform the tasks using the sensors, controllers, etc. Network embedded systems are usually general-purpose processors.
2. Mobile embedded systems
Mobile-embedded systems are embedded in mobile phones, cameras and are usually smaller in size. However, embedded systems in mobile application development typically lack an excellent UI and create memory issues.
3. Real-time embedded systems
Real-time embedded systems are mainly designed to perform a specific task within a pre-determined time. There are two types of real-time embedded systems; soft real-time embedded systems and rigid real-time embedded systems.
4. Stand-alone embedded systems
Stand-alone embedded systems work by receiving the input without using any ghost system, is processed, and you get the desired output.
Characteristics and Features of Embedded Systems
1. The most prominent characteristics of embedded systems are that they are task-specific.
2. Apart from being task-specific, they are designed to perform a job at a pre-specified time without making any errors.
3. They have zero user interfaces as microcontrollers and microprocessors create them.
4. Embedded systems are affordable, smaller in size, and take up less power to perform the tasks.
5. They are reliable as well as scalable for a relatively long duration.
6. Using the connected peripherals, embedded systems attach the input and output devices.
7. Last but not least, the hardware embedded system is applied for security and performance, whereas the software highlights the features.
Considerations while Implementing an Embedded System Design?
Platforms, Language, and Tools
Building enterprise applications and building embedded systems are poles apart. In the former case, the developer may choose a platform depending on the client requirements but is spoilt for choice regarding tools, languages, and databases. On the other hand, in the case of embedded systems development, options are few and far between. Embedded code functions at the hardware level, and hence hardware manufacturers will influence the choice of platforms, language, and tools.
Limitations of Embedded Systems
Hardware design imposes limitations on embedded systems; for example, it is impossible to increase memory or go for a quicker processor, even if you want to. Similar to an enterprise application development, a software developer cannot seek more memory. So it becomes the project manager’s responsibility to ensure developers do not cross the line imposed by the hardware design. Since the very beginning, embedded systems haven’t had many security features. Embedded systems are prone to breaking down, but most of them are reliable.
Compatibility and Integration Testing
Some embedded systems need precision as they can be the determiner oflife and death, for example, in the medical equipment industry. Thus, testing some embedded systems is of utmost importance. In embedded systems, the software has to work with hardware coordinately, which increases complexity. Developers need to understand how a complete system will work, rather than just the software and electrical parts.
Advantages of Embedded Systems
As embedded programming always does the same essential task, there is little need for replacing hardware. Being dedicated to a particular job does not get interrupted by other requests. An embedded system can even run on an old OS and without any updates. The processors to be used might not need to be sophisticated, which can bring down overall operation costs.
Why should we use Embedded Systems?
Embedded systems are the most reliable and flexible way to make use of technology. Users can stick to their idea using microprocessors, microcontrollers, and FPGA chips to spend so little on it. Embedded systems development has made it easier for everyone to use embedded solutions just by implementing their ideas.
