Firmware is found in a wide range of computing devices including personal computers, phones, home appliances, vehicles, computer peripherals and in many of the digital chips inside each of these larger systems. Firmware is stored in non-volatile memory – either read-only memory (ROM) or programmable memory such as EPROM, EEPROM, or flash.
They can use different I/O protocols, but SPI is the most common. Unified Extensible Firmware Interface ( UEFI, / ˈjuːɪfaɪ / or as an acronym) [ b] is a specification that defines the architecture of the platform firmware used for booting the computer hardware and its interface for interaction with the operating system.
An embedded controller can have the following tasks: Receiving and processing signals from the keyboard [ 1] and the touchpad (including touchpad disable) Other buttons and switches (e.g., power button, laptop lid switch (received from hall sensor)) [ 2] Controlling access to the A20 line [ 3] Thermal measurement (CPU, GPU, Motherboard) and ...
UEFI. In computing, BIOS ( / ˈbaɪɒs, - oʊs /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).
