Introduction
In today’s smart electronics and devices, you have probably come across two words: firmware and embedded software. Both these concepts are closely related, and in some instances, attached to the same word. However, they are not identical. If you deal with electronics at any level, engage in embedded product development, or have developed an interest in knowing how your device works, distinguishing embedded software from firmware is vital.
In this article, we will outline giving clear meanings of what is firmware vs embedded software are, how they are applied, and highlight their main differences.
What is Firmware?
Firmware is one type of software that a device’s hardware comes pre-loaded with. It serves as the interface between higher-level software applications and the device hardware. Normally, firmware is retrieved from a non-volatile memory device such as ROM (Read-Only Memory), EEPROM, Flash memory, and so on.
Key Characteristics of Firmware:
- Basic control over the hardware operations of the equipment.
- Commonly written in C or assembly language.
- Not frequently updated, although some up-to-date devices support updates.
- Specific in purpose, primarily targeted at related hardware operations.
Common Examples of Firmware:
- Firmware associated with your television remote control.
- The computer’s so-called startup code (BIOS or UEFI).
- Firmware contained in printers, routers, and washing machines.
It is firmware that dictates how your hardware will perform. In the absence of firmware, a device would not know how to turn on or how to interact with other components.
What is Embedded Software?
Embedded software is in marked contrast to firmware because it is a type of software that is designed to work in a system that has a dedicated device; that is, computing systems inside devices that are not classified as a computer.
Compared to firmware, embedded software is intricate, multifunctional, and at times, even houses an operating system such as Linux or RTOS.
Key Characteristics of Embedded Software
- Tailored for use in embedded systems, smart thermostats, digital watches, and industrial robots among others.
- They can be improved upon, reworked, or added to.
- They are mostly designed in C, C++, or Python.
- They can operate on real-time operating systems (RTOS).
Common Examples of Embedded Software:
- Controls a digital camera’s interface as well as processes images.
- The operating system within a smart thermostat.
- Software within a car’s infotainment system or engine control unit (ECU).
Expressing it literally, embedded software works as the command center of an item with various functionalities because it controls its operations.
Difference Between Firmware vs Embedded Software
| Feature | Firmware | Embedded Software |
|---|---|---|
| Definition | Deep rooted, Low Level Software interacts with the hardware closely | Software meant to manage, control embedded systems |
| Functionality | Communication and control on a basic level | Interaction with the user, multitasking, complex logic on an advanced level |
| Storage | ROM, EEPROM, Flash memory | Memory components, can contain OS |
| Flexibility | Updates are quite limited, fixed flexibility | Updated frequently, more flexible |
| Programming Language | Uses C and assembly primarily | C, C++, Python and more |
| Complexity | Simpler in nature | Includes more components and devices like GUI |
| Examples | BIOS, remote controls, and printer firmware | Industrial machines, smart TVs, smartwatches |
Collaboration
Both firmware and embedded software work together within the same embedded system. Consider a smart home device:
-
Firmware manages sensor connections, hardware initialization, and power management.
-
Your main application logic, sending alerts to smartphones after interpreting sensor data, is managed by embedded software.
Think of the structure glued with the foundation, and in this scenario, embedded software is the structure whereas firmware serves as the foundation.
Understanding Why the Distinctions Matter
If you are a developer, product manager, or a hardware designer, understanding firmware and embedded software helps you:
-
Communicate without misunderstandings across teams.
-
Design more advanced products.
-
Properly plan for software upgrades.
-
Make the right selection of development tools.
This is vital in sectors like automotive, consumer electronics, industrial automation, and IoT (Internet of Things) due to the ubiquity of embedded systems.
Key Takeaways
The operation of modern devices relies heavily on firmware and embedded software. Even though there are overlaps between the two, they differ substantially in functionality, complexity, and capabilities.
-
Embedded software executes the logic and commands that are responsible for the main functions of a device.
-
It also aids in making intelligent decisions regarding design, development, and troubleshooting.
