If you’re not in the tech world, you may not be familiar with all the different names used when talking about computer programming and how software is handled. Right now, the biggest two buzzwords are firmware and embedded software, and it can seem like they’re the same thing, even though their definitions differ quite a bit. What are these things? And what’s the difference between firmware and embedded software? That’s what this guide will explain!
What Are Firmware and Embedded Software?
Firmware is a type of software that is embedded in a hardware device. It is responsible for controlling the device and its functions.
Embedded software, on the other hand, is a type of software that is designed to perform a specific task.
It is often found in devices that require real-time processing, such as IoT solutions. There are two main types of embedded software: real-time operating systems (RTOS) and application programming interfaces (API). RTOS is used when the timing is important, while API usually provides more flexibility.
The Similarities in Functionality
Both firmware and embedded software are used in IoT solutions. They are both read-only memory that can be stored in devices like controllers, processors, and chips. Both are executed by machines and help give instructions to perform a specific function.
The main difference between firmware and embedded software is how they’re created and what language they’re written in. Firmware development is usually developed in C or C++, while embedded software can be developed in any programming language.
Other Differences
Firmware is embedded software written onto read-only memory (ROM). IoT solutions often use firmware because it can’t be accidentally erased or overwritten.
On the other hand, embedded software is stored in random access memory (RAM). This means that it can be updated more easily, but it’s also more vulnerable to power outages and data loss.
Overall, firmware is more permanent, and embedded software is more flexible. These two programs are usually developed for different purposes, so it makes sense that they have their own unique benefits and drawbacks.
Examples of Firmware
- Firmware is a type of software that is embedded in a hardware device.
- Examples of firmware devices include routers, TVs, printers, and digital cameras.
- Firmware is responsible for booting the device and running low-level tasks.
- It is stored in read-only memory (ROM), so it cannot be accidentally erased or modified.
- Updating firmware can be difficult and sometimes requires special equipment.
- Rolling back to a previous version of firmware is also not always possible.
Because of these reasons, it is important to choose firmware wisely as it can be very difficult to change later.
Examples of Embedded software
Most people have heard of firmware, but not everyone is familiar with embedded software. Here are some examples of embedded software:
- The BIOS on a computer is a type of firmware.
- The controller in a game console is a type of embedded software.
- The software that runs your car’s engine is another type of embedded software. It can tell when you turn on the ignition, adjust how much fuel to use, calculate the best time to change gears, and more.
- Embedded software also includes an operating system (OS) other than Windows or Mac OS X. Examples include Android, Linux, and iOS.
Is firmware part of embedded software?
Firmware is software embedded into hardware, meaning it’s written onto read-only memory (ROM) chips. Many electronic devices, including computers, TVs, and printers, are ROM chips. The device can’t function without firmware because it provides instructions to tell the computer what to do when you turn on your device. Here you will get the complete guide about how to build a strong team of embedded software.
Is firmware engineer the same as embedded software engineer?
No, a firmware engineer is not the same as an embedded software engineer. The main difference between the two is that firmware engineers focus on developing code stored in non-volatile memory. In contrast, embedded software engineers focus on developing code that is stored in volatile memory.
Final Thoughts
In short, firmware is software embedded in a hardware device. It is responsible for low-level tasks such as booting the device and providing basic functionality. On the other hand, embedded software is application software specifically designed to run on embedded systems. It generally has a more complex set of features than firmware.
