What is an Embedded System?

An embedded system is a specialized computer system that seamlessly integrates hardware and software to perform a specific task or function. It utilizes a microcontroller to perform mathematical operations, such as those facilitated by an FPU, and communicate with the outside world through various interfaces, such as GPIO, ADC, CAN, and SPI. These systems are often run on real-time operating systems (RTOS) or Linux, and employ digital cryptography for security. They can also interact and exchange data with other operating systems and cloud services like Azure or AWS.

According to Global Market Insights the market share of embedded systems, estimated at more than $140 bilion in 2022, has grown this year and is projected to reach $ 250 billion by 2032. Therefore, to match the growing needs bussines go above and beyond to create better-embedded systems for a lower price. They implement bigger capacities, and more efficiency, making them more specialised and faster.

Basic Embedded System Structure

Understanding the critical components of Embedded systems is essential for choosing the right fit for your project. It also helps you to beter understand the development proces and to plan your software. They are a specialized combination of hardware and software, designed to perform a specific function.

Hardware Components:

  • Microcontroller or Microprocessor:

It is the Hart of the embedded system responsible for executing instructions and controlling the system’s behaviour. The choice of microcontroller depends on the system’s processing power, memory, and peripheral interface requirements.

  • Memory:

The part where the system stores data and instructions is typically divided into Read-Only Memory (ROM), Random Access Memory (RAM), and flash memory. Different types of memory offer different benefits, such as fast access time or non-volatility. So when choosing this component, it is crucial to consider the needs.

  • Peripheral Devices:

Sensors, actuators, and displays are peripheral devices that interact with the environment and provide information to the user. These devices are connected to the microcontroller through various interfaces, such as analog-to-digital or digital-to-analog converters.

  • Power Management:

An embedded system must have a reliable power source, typically provided by batteries or power supplies. Power management involves controlling the power consumption of the system and optimizing battery life.

  • Communication Interfaces:

They allow the embedded system to exchange data with others, such as embedded systems, computers, or networks. Examples of communication interfaces include serial, parallel, and network interfaces, such as Ethernet or Wi-Fi.

Software Components:

  • Operating System (OS):

It manages system resources and includes device drivers to facilitate communication between software and hardware components. There are general-purpose and real-time OS options.

  • Device Drivers:

They are software components that allow the operating system to interact with hardware devices, such as sensors or displays. They act as intermediaries between the hardware and software, translating the hardware’s behavior into a form the software can use.

  • Application Software:

The application software defines the specific functionality of an embedded system and provides the user with a means to interact with it. The software is usually written in a high-level programming language, C or Python, and is compiled for the target system.

  • Firmware:

A special type of software that is programmed into read-only memory (ROM) and is used to control the basic behavior of the hardware. The firmware provides a low-level interface between the hardware and the operating system.

  • Libraries and Middleware:

They are collections of pre-written code that provide standard functionality, such as communication protocols, encryption, or data processing. These components help reduce the development time and complexity of embedded software.

What are the Types of Embedded Systems?

To fulfil diverse requirements in various applications embedded systems have different types. For instance, some require low power consumption, while others prioritize real-time processing capabilities. Hence, embedded systems come in various forms to cater to the unique demands of different fields, such as automotive, healthcare, and consumer electronics.
They can be classified into two main factors:

1. Performance and Functional Requirements

Embedded systems with a real-time focus are critical components in industries where timely responses are vital. Whether it’s defense, healthcare, or others, these systems are designed to deliver the output within a defined time frame, making them the go-to solution for time-sensitive tasks. They come in two varieties: Soft Real-Time, where deadlines are more flexible, and Hard Real-Time, where punctuality is key. When every second counts, these systems rise to the challenge, ensuring accuracy and efficiency in the most demanding situations.

  • Stand Alone Embedded Systems :

Stand-Alone Embedded Systems are independent and operate without a host. They process input in digital or analog form and produce output accordingly. Ideal for applications requiring independence, these systems simplify processes, reduce dependence, and improve control and efficiency. They are a smart choice for standalone solutions in business or home environments and can usually be used for MP3 players, microwave ovens or calculators.

  • Connected Embedded Systems:

These systems, equipped with either wired or wireless connections, output information to linked devices. Communication with an on-board web server enables data exchange via the network, providing enhanced versatility compared to standalone Embedded Systems. They are primarily used in home security systems, ATM machines and card swipe machines.

  • Mobile Embedded Systems:

For solutions that require the least amount of resources the choice is usually to use mobile embedded systems. They are compact and user-friendly and the most popular choice among others due to their ease of use. Additionally, their portable design makes them ideal for on-the-go applications and situations where mobility is key.

3. Performance and Micro-controllers

  • Small-Scale Embedded Systems:

Crafted with 8-bit or 16-bit micro-controllers, these systems deliver exceptional performance with minimal memory and processing speed requirements. Despite relying on battery power, they serve as crucial components in computer systems, dedicating their functions to specific tasks without acting as standalone entities.

  • Medium-Scale Embedded Systems:

Fueled by 16-bit or 32-bit microcontrollers, these systems boast improved speed compared to their small-scale counterparts. Complex hardware and software integration make programming these systems challenging, utilizing languages like Java, C, and C++ to develop their functionality. Developers also employ various software tools, including compilers, debuggers, and simulators, to bring these systems to life.

  • Sophisticated or Complex Embedded Systems:

Sophisticated or Complex Embedded Systems are designed using multiple 32-bit or 64-bit micro-controller. These systems are developed to perform large-scale complex functions. These systems have high hardware and software complexities. We use both hardware and software components to design final systems or hardware products.

Difference Between Firmware, Embedded Software and IoT

Many of other systems and devices may seem similar to embedded, but don’t let that fool you. Understanding the practical differences between firmware, embedded software, and IoT is crucial.

The IoT, or the Internet of Things, describes the interconnected network of physical devices and everyday objects that collect and exchange data, utilizing firmware and embedded software. On the other hand, firmware controls a device’s basic functions and resides permanently in its memory. Embedded software, integrated into a device’s hardware, carries out specific tasks. They both determine a device’s basic functionality and performance, while the IoT influences the device’s connectivity and integration into larger systems.

Understanding these differences can inform product development and implementation strategies, ensuring devices function as intended and meet customer needs. It can also impact supply chain management, as the use of firmware and embedded software can affect a device’s compatibility with other systems and the ability to receive updates.SolveQ experience in embedded systems
