Embedded systems are often perceived as a specialized area within computer engineering because they involve developing computer systems dedicated to performing specific tasks within larger systems. These tasks can range from controlling household appliances to managing complex industrial processes.
However, despite this perception of specialization, embedded systems actually have a broad impact across various industries and applications. They are integral components in various devices, including smartphones, automotive electronics, medical devices, home automation systems, and industrial machinery.
Given the increasing integration of technology into our everyday lives and the continued demand for smarter and more interconnected devices, one might contemplate whether pursuing a career in embedded systems is a viable and rewarding choice. The unequivocal answer is YES
Pursuing a career in embedded systems is definitely worth your while; a calling that promises fulfillment and meaningful contributions to the future of technology.
So, if you’re wondering where to steer your career compass, embedded systems could very well be the promising destination you’ve been looking for. Before we delve further into the reasons to consider a career in this field, let’s explain what it entails.
What is Embedded System Engineering?
Internet of Things (IoT) devices cannot function without Embedded systems
Embedded system engineering is a discipline that focuses on designing, developing, and implementing embedded systems. An embedded system is a computer system specifically designed for a single and dedicated purpose. They’re embedded within larger mechanical or electrical systems to fulfil a specific task. Examples of such systems include microcontrollers in washing machines, automotive engine control units, the firmware in a smart thermostat and IoT devices.
An embedded engineer designs, develops and maintains embedded systems within various devices. This role often involves software development. However, a comprehensive understanding of the entire embedded system is essential for success in this role. Hardware considerations, such as selecting appropriate microcontrollers or processors, designing circuits/interfaces, and managing power consumption are also vital aspects of embedded system design.
The specific responsibilities of an engineer can differ between organizations, as the term “embedded engineer” is used broadly and may encompass varying scopes of work. Some companies use the title to refer specifically to engineers working primarily on embedded software, while others emphasize a more holistic involvement with the entire system.
In this capacity, an embedded engineer is tasked with working on embedded systems designed to fulfill specific functions. Beyond software development, the engineer may also contribute to comprehensive system testing to ensure and validate its functionality.
Additionally, they face challenges such as limited resources (memory and processing power), real-time requirements, and reliability considerations while integrating the embedded system with the larger mechanical or electrical system.
Trends in Embedded Systems For 2024
Embedded systems are evolving rapidly due to the increasing demand for smart and interconnected devices. In 2024, several exciting advancements are expected in the industry. Here are some trends we anticipate to be fully adopted in the development of embedded systems in 2024.
- Utilizing Artificial Intelligence for Embedded Software Development: Artificial intelligence (AI) technologies will offer significant potential for optimizing various aspects of embedded software development. AI tools like ChatGPT, Google Gemini or Copilot in GitHub can be used to generate human-readable code easily. This will speed up the embedded development process as developers will spend less time writing codes. These AI tools can also assist in debugging and even in code reviews, as they can easily identify and fix errors in codes in split seconds.
- Improving Continuous Integration/Continuous Deployment (CI/CD): ProcessesCI/CD practices are essential for streamlining embedded software development, testing, and deployment. While these practices have existed for some time, they have not been fully implemented in the embedded systems development process. We expect the automation of build, test, and deployment processes to ensure consistency and efficiency in embedded software development. This will minimize the rate of manual errors and also accelerate time-to-market.
- Using POSIX APIs in Real-Time Operating Systems (RTOS): Portable Operating System Interface (POSIX) is a set of standards that define how operating systems should behave, especially in terms of system calls, command-line interfaces, and utility interfaces. It aims to make software more portable across different operating systems by providing a common set of interfaces.
Using POSIX APIs in Real-Time Operating Systems (RTOS) can make creating embedded applications that work across different devices easier. It’s like having a common language for writing software that runs on various platforms. By supporting POSIX, Real-time operating systems can offer flexibility and simplify developing software for embedded systems.
- Embracing Model-Based Design, Containerization, and Virtualization: Model-based design will enable developers to create high-level models of embedded systems, which can be simulated, verified, and automatically translated into code. Containerization and virtualization technologies, on the other hand, will provide efficient and scalable development environments by offering isolated and reproducible settings for developing and testing embedded software.
- Adopting DevOps and CI/CD Practices: DevOps promotes collaboration, automation, and continuous improvement throughout the software development lifecycle. Integrating DevOps with CI/CD pipelines in embedded systems development will enhance teamwork, automate tasks, and improve software delivery efficiency and reliability. This will result in higher-quality releases and increased adaptability to changing requirements and market demands.
