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.
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]
Java SE embedded is based on desktop Java Platform, Standard Edition. [1] It is designed to be used on systems with at least 32 MB of RAM, and can work on Linux ARM, x86, or Power ISA, and Windows XP and Windows XP Embedded architectures. Java ME embedded used to be based on the Connected Device Configuration subset of Java Platform, Micro ...
An embedded system on a plug-in card, featuring a processor, memory, power supply, and various external interfaces. An Embedded Operating System (EOS) is an operating system designed specifically for embedded computer systems. These systems aim to enhance functionality and reliability to perform dedicated tasks.

Crosstool is a helpful toolchain of scripts, which create a Linux cross-compile environment for the desired architecture, including embedded systems; crosstool-NG is a rewrite of Crosstool and helps building toolchains. buildroot is another set of scripts for building a uClibc-based toolchain, usually for
The principal advantage of the pure Harvard architecture—simultaneous access to more than one memory system—has been reduced by modified Harvard processors using modern CPU cache systems. Relatively pure Harvard architecture machines are used mostly in applications where trade-offs, like the cost and power savings from omitting caches ...

Some low-cost processors used in embedded systems do not provide a memory management unit (MMU). In addition many embedded systems are real-time systems and overlays provide more determinate response-time than paging. For example, the Space Shuttle Primary Avionics System Software (PASS) uses programmed overlays. [5]
