Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems. It is typically specialized for the particular hardware that it runs on and has time and memory constraints. [1] This term is sometimes used interchangeably with firmware. [2]
This category includes articles about all aspects of embedded systems: various systems, constituent components, uses, development tools, etc. For classes of software/devices, the category, if existent, or the relevant general article, is preferably included instead of each actual item.
Embedded software requires storage for executables and temporary data processing during runtime. Embedded systems typically utilize ROM and RAM as main memory components. For functionality, embedded systems necessitate input and output interfaces. Embedded hardware configurations are often unique, varying according to the application. [4]
The majority of microcontrollers in use today are embedded in other machinery, such as automobiles, telephones, appliances, and peripherals for computer systems. While some embedded systems are very sophisticated, many have minimal requirements for memory and program length, with no operating system, and low software
An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
In January 2011, AMD announced the AMD Embedded G-Series Accelerated Processing Unit. [245] [246] This was the first APU for embedded applications. These were followed by updates in 2013 and 2016. [247] [248] In May 2012, AMD Announced the AMD Embedded R-Series Accelerated Processing Unit. [249]
Computer operating systems based on the Linux kernel are used in embedded systems such as consumer electronics (eg. set-top boxes, smart TVs and personal video recorders (PVRs)), in-vehicle infotainment (IVI), networking equipment (such as routers, switches, wireless access points (WAPs) or wireless routers), machine control, industrial automation, navigation equipment, spacecraft flight ...
Many software functions would be moved to microcode, and instruction sets could be customized, with different firmware loaded for different instruction sets. [ 3 ] As computers began to increase in complexity, it became clear that various programs needed to first be initiated and run to provide a consistent environment necessary for running ...
