What is firmware and how is it utilized in embedded systems?

1 Answer

by
Firmware refers to a type of software that is specifically designed to be permanently programmed into a hardware device, often in read-only memory (ROM) or flash memory. It serves as the intermediary layer between the hardware components of a device and the higher-level software applications that run on it. Firmware is responsible for controlling and managing the hardware's functionality and behavior.

Embedded systems are specialized computing systems that are designed to perform specific tasks or functions. They are often found in various devices and appliances, such as microwave ovens, washing machines, digital cameras, routers, and even more complex systems like automotive control units and medical devices. These systems have limited resources compared to general-purpose computers, which makes them efficient for their dedicated tasks.

Firmware is utilized in embedded systems in several ways:

Hardware Initialization: Firmware is responsible for initializing and configuring the
