The Main Types of Embedded Systems
Here at Waverley, we have delivered multiple embedded software solutions to clients from a variety of industries. Hence, our embedded software engineers have first-hand experience with different types of these platforms.
Let’s get started with the basics, and define the embedded systems. They are simply a combination of computer hardware and software tools. Explicitly, the term refers to hardware embedded with a particular kind of software to perform a definite function.
Embedded systems can be independent or work as part of a larger platform, but whatever the case may be, each unit is programmed to carry out a specific task. Often, they will be used to monitor the performance and operations of the device they are embedded into. Thus, helping ensure that everything works properly.
There are many different types of embedded systems and device classifications based on the types of embedded systems, performance, or functionality. Let’s look deeper into those classifications.
The Main Classification of Embedded Systems
Based on performance and functional requirements these are the main systems: network, mobile, and standalone. As a separate entity, we will talk about real-time embedded systems, which could be divided into soft and hard versions.
Based on the performance of the microcontroller we could define 3 types of embedded system software such as small-scale, medium-scale, and sophisticated.
Additionally, specialists can categorize embedded systems based on battery life duration.
- Real-Time Embedded Systems
This kind of embedded software needs to deliver outputs promptly, within a particular time frame. Hence, it is often used in time-sensitive sectors like transportation, manufacturing, and even healthcare, as all of these spheres rely on delicate processes to perform their business. Some examples of real-time embedded systems are aircraft or autonomous vehicle controls, and traffic monitoring tools.Real-time embedded systems can be broken down into ‘soft’ and ‘hard’ categories. The former refers to those in which the time frame doesn’t need to be strictly followed. That is to say, if the deadline of a particular task had passed and the system didn’t produce the needed result in time, the output would still be accepted. Conversely, in the case of hard real-time embedded systems, the time frame has to be followed strictly and if the deadline is not met, the result may not be accepted. Let’s check the examples in detail:
- Soft real-time embedded systems: temperature or humidity monitoring tools. A minor delay in the acquisition of real-time temperature data might not be considered too critical, and obtaining the information a bit later will still be valuable.
- Hard real-time embedded systems: aircraft control platforms. In this case, even a small delay in data acquisition can lead to disastrous consequences as the pilot might make a decision based on outdated information.
- Standalone Embedded Systems
This type of embedded software can work by itself, without requiring a host like a computer or processor. It simply takes input data in its digital or analog form and delivers an output that might be displayed through a connected device.Instruments like cameras, digital watches, and MP3 players are all examples of standalone embedded systems. They work by themselves, without relying on a larger platform.
- Network Embedded Systems
This type of embedded system relies on wired or wireless networks for output generation. Often, these kinds of platforms are built on general-purpose processors and consist of various components like sensors, controllers, and the like.The most popular examples of network-embedded systems are home or office security systems, point-of-sale tools, and ATMs. All of these solutions rely on networks of other devices to carry out their function. For instance, a security system includes sensors, cameras, alarms, and similar gadgets to monitor for intrusions and alert the security staff.
- Mobile Embedded Systems
Mobile embedded systems are portable and easy to move around. Typically, they are used in different kinds of mobile devices but naturally have some constraints when it comes to memory size. Despite the memory and functionality limitations, mobile embedded systems are quite popular solely because they work on the go.The classification based on the microcontroller performance is not the main one, but it helps in understanding the complexity, functionality, and resource requirements of various embedded systems.
Embedded systems: Microcontroller Performance
| Small-Scale Embedded Systems | Medium-Scale Embedded Systems | Sophisticated Embedded Systems |
|---|---|---|
These systems are designed using an 8-bit or 16-bit microcontroller and can be powered by a battery. In this case, the processor leverages very little memory resources and works at a limited speed. Small-scale embedded systems are typically used in devices that have basic functions such as temperature monitoring, simple displays, and basic input/output operations. | This category is developed with 16-bit or 32-bit microcontrollers. Naturally, these embedded systems are faster and somewhat more complex than the small-scale ones. For example, these systems are often used in devices that require more complex functions like digital signal processing, data storage, and UI control. | Sophisticated systems work on multiple algorithms and have complex hardware and software components. Often, they require a processor that can be configurable. These solutions are designed using various 32-bit or 64-bit microcontrollers and require a lot of memory to perform well. |
Embedded systems can be classified based on their battery life duration, which significantly impacts their design, application, and usage scenarios.
| Short-Term Battery Life Systems | Medium-Term Battery Life Systems | Long-Term Battery Life Systems | Ultra-Long-Term Battery Life Systems |
|---|---|---|---|
| Duration: Hours to days | Duration: Days to weeks | Duration: Weeks to months | Duration: Months to years |

Parts of Embedded Software Systems
From the smartphone in your hands to the home or kitchen appliances, and even the sophisticated machinery in industrial settings – embedded systems are the hidden heroes that make everything work.
The components of an embedded system include a combination of hardware and software. The hardware consists of microcontrollers/microprocessors, and memory, on the other hand, the software part includes the system software, application software, and the OS (most systems are using RTOS). Separately we can define interface components such as input/output devices (such as sensors, actuators, and displays), and various interfaces for connectivity.
Embedded software engineers declare that hardware and software components both make up an embedded system. It also goes by the name ‘firmware’ when it performs certain tasks. The employment of embedded systems has impacted every aspect of daily life.
Hardware Components of an Embedded System
| Hardware Component | Characteristics |
|---|---|
| Power Supply | The system will either have its own power supply or, if it is a component of a larger system, it will draw power from that system. Donate to a system that the embedded system interfaces with, like a network card. |
| Processor | Any embedded system’s core component is the CPU. It determines how well the system works. There are many categories of processors. One of the classifications divides processors into 8-bit, 16-bit, 32-bit, or 64-bit CPUs. For embedded systems, smaller applications require fewer bits. Large applications call for embedded systems with larger bit processors. The most commonly used processors are microprocessors and microcontrollers. |
| Timers Counter | Some applications need a delay, such as LED display apps, which need one so that the LED can keep blinking. Timers are employed for this reason in embedded systems. Mechanisms are often required in embedded systems to count the occurrence of things and carry out actions at regular intervals. Time boundaries apply to embedded systems when counting the number of events or the interval between them. |
| Memory | The microcontroller itself contains two different types of memory: RAM and ROM. ROM is a code memory, whereas RAM is a volatile memory. In embedded systems, several types of system memory exist, including internal memory at the microcontroller, RAM at the system on a chip or external RAM, internal caches at the microprocessor, external RAM chips, ROM / PROM, and Flash / EEPROM. |
| The Communication Port | You can communicate with other embedded systems via this interface. Various communication interfaces are available in embedded systems, including UART, USB, Ethernet, RS-485, and many more. A serial port is an interface for serial communication in which data is transferred one bit at a time. The serial protocols UART, SPI, SCI, and I2C are often used. |
| Parallel Port | Peripheral connections are made via a parallel port. The term alludes to the method of data transmission, where parallel ports send several bits of data simultaneously. In comparison to modern serial ports, parallel ports have more data lines and require longer cables and port connectors. |
| Output And Input | Input is necessary to communicate with the embedded system. Inputs can include a keyboard, touchpad, camera, microphone, GPS, and various sensors. An output device is a hardware component that connects to a primary device, such as a computer and transforms received data from the processing unit into a human-perceptible form that users can understand and use. This can be text, graphics, audio, or video. |
Software Components of Embedded System
As it was covered hardware and software modules come together to form an embedded system. Now let’s focus on the software components. Software for computers and embedded systems serves quite distinct functions. Computer software can be placed on various devices to accomplish the desired goals. However, embedded system software is created for a given device to accomplish a given goal.
| Software Components | Characteristics |
|---|---|
| IDE (Integrated development environment) | The first tool you need for embedded system software is an editor. The text file you create in the editor will contain the code you write using any suitable programming language. |
| Emulator | An emulator is a piece of software that enables you to use the features of the host system. All the parts are controllable through the emulator tool. The emulator is also used to debug applications. The primary function of the emulator is to simulate a genuine system’s behavior in the embedded system. You may simulate how the code will operate in real time by using an emulator. |
| Compiler | The written programs that translate source code from a high-level programming language into a low-level programming language are referred to as ‘compilers.’ A compiler is a piece of software that transforms a programming language into a language the target machine can comprehend and use to execute the functions. |
| Assembler | The assembler works when the programming language used to create the application is assembly language. After that, the assembly language program is converted to HEX code so it may be processed further. After the code is written, the programmer is used to write the program into the chip. |
| Linker | Software is written in discrete modules and components called ‘linkers.’ A linker, often known as a link editor, is a program that merges one or more object files into a single executable code. |
| Debugger | A debugger is a tool used for testing and debugging. It examines the code, finds where errors and problems are, removes them, and notes their locations. Programmers can confront and correct mistakes rapidly. |
Embedded Software Architecture: 3 Main Components
To fully cover the topic we should pay attention to the embedded software development process, especially, software architecture and embedded programming software.
Let’s start with the software architecture. Here we need to take into consideration 3 main components: operating system, device drivers, and application software.
- Embedded Operating System:
Depending on the complexity of the embedded system, an operating system (OS) may or may not be present. Real-time operating systems (RTOS) are common in applications requiring precise timing and responsiveness. For simpler systems, a bare-metal approach may be adopted, where the software directly interacts with the hardware. - Device Drivers:
Device drivers act as a bridge between the operating system and the hardware, facilitating communication and control. Well-designed device drivers are crucial for efficient utilization of hardware resources and ensuring seamless operation. - Application Software:
The application software is tailored to the specific functionality of the embedded system. This software layer defines how the system responds to inputs, processes data, and generates outputs. Optimization is key to ensuring that the application software meets performance requirements within the given hardware constraints.
The embedded programming software mainly focuses on low-level programming, hardware-software interaction, real-time constraints, and optimizing for limited resources (such as memory and processing power).
Embedded Software Development Process
The embedded software development process is similar to the software development processes in general but it has certain specific features. We will guide you through the steps of the process.
1. Define the Product Specs
The first step in the embedded software development procedure is collecting all the possible data. The product should answer these questions:
Problem – What problems does the product solve? What value will it bring to the customer’s life?
2. Structural Architecture
The software architecture includes:
- The final cut of the design
- Strategies involved
- Type of wired or wireless connectivity to be used
- Type of power supply
- How the hardware design will look like
- Web app/Cloud-based app/Desktop software/Mobile app design
On the contrary, the hardware design involves selecting the specific component for every aspect of the circuit’s parameters. Combining the architecture blueprints, one can get closer to executing this flow chart in the embedded systems development process.
3. PoC / Prototype Development
PoC is specially drafted to note the details of the prototype software. In this stage, quality experts develop and thoroughly test the prototype. It is crucial to first develop a prototype, ensure its topmost quality, and collect feedback.
4. Testing & Field Trials
Products that give perfect results during lab testing sessions but don’t perform up to the mark when on the field. Therefore, it’s recommended that hardware QA testing be conducted in the proper environment. Waverley’s specialists have profound experience in providing stress hardware QA tests.
5. Product Release
Now that the product is ready to be launched into the outer world for startup and enterprise use the only thing to be done is to get the hardware product certification that will be managed using this embedded software.
