Embedded System Glossary – F

Embedded System Terminology - F

Farad - The unit of measurement in which capacitance is measured.
Field Programmable Gate Array (FPGA) - A type of programmable ASIC implementing the application specific ISA model.
Firmware - Any software stored on ROM.
Flash - To download new firmware in to a flash memory
Flash Memory - A CMOS-based faster and cheaper variation of EEPROM. Flash can be written and erased in blocks or sectors (a group of bytes). Flash can also be erased electrically, while still residing in the embedded device.
Flip-Flop - One of the most commonly used types of latches in processors and memory circuitry. Flip-flops are sequential circuits that are called such because they function by alternating (flip-flopping) between both states (0 and 1), and the output is then switched (such as from 0-to-1 or from 1-to-0, for example). There are several types of flip-flops, but all essentially fall under either the asynchronous or synchronous categories.
Fuse - An electrical component that protects a circuit from too much current by breaking the circuit when a high enough current passes through it. Fuses can also be used in some types of ROMs as the mechanism to store data.
Fuzzy Logic - A methodology that makes it possible to make decisions based only on ambiguous or imprecise input data. Fuzzy logic can be implemented in software or hardware.
