The Essence of Embedded Software
Embedded software is specialized programming placed into a chip or on firmware to govern the operations of a device or system it’s embedded into. Similar to how a computer’s operating system manages software applications, embedded software governs device operations.
However, embedded software has fixed hardware requirements and capabilities, unlike PC applications, which may be run on various computer systems and modified to offer varying levels of functionality. Embedded software is designed specifically for the device it operates on, with processing and memory constraints directly tied to the device specifications.
For instance, Google makes it extremely easy to install Google Meet on any device and conduct video calls. It doesn’t matter if it is a phone, tablet, or laptop – as long as the device meets the requirements for video calls with Google Meet. In contrast, no other camera in your home can leverage the technical capabilities of your Ring doorbell.
Thus, products with embedded software are extremely specific and have somewhat limited functionality.
Common day examples of embedded software include:
- TV remote control
- Digital camera
- Traditional calculators
When you realize something as simple as a TV remote has embedded software, you’ll appreciate just how pervasive yet invisible embedded software is. In the TV remote, the embedded software interprets the buttons you press(volume control, channel switching, power on/off, and other special features) and sends the appropriate signals to the TV.
The components supporting functions of embedded software are united in what’s known as an embedded system – meaning embedded software is a subset of an embedded system. Namely, an embedded system is a combination of hardware elements in a device that operates using embedded software.
To create an embedded system, you need embedded software engineers. These tech experts literally open the door to the world of embedded software development.
The Craft of Embedded Software Development
Embedded software development is the process of designing, developing, and managing software integrated into hardware devices such as microcontrollers or other embedded systems.
Since these types of software are specifically made to control the operation of the hardware they are embedded in, they typically require a deep understanding of the capabilities and limitations of the hardware.
This differs from traditional software development, which entails designing and maintaining software applications…
To begin with, software developed with traditional software development techniques is not limited to any particular hardware device or component. Such software is for general-purpose computing hardware i.e, personal computers or servers. In contrast, embedded software is typically designed to run on a microprocessor or microcontroller integrated into the hardware.
Additionally, developing embedded software differs from traditional software in terms of methodology. Namely, debugging and testing are conducted frequently during embedded software development to ensure the program complies with real-time constraints and runs efficiently on limited resources. While testing is still essential for traditional software development, it’s less rigorous than embedded software development.
