  Embedded system - Wikipedia, the free encyclopedia
Embedded systems reside in machines that are expected to run continuously for years without errors, and in some cases recover by themselves if an error occurs.
A common configuration for very-high-volume embedded systems is the system on a chip, an application-specific integrated circuit, for which the CPU was purchased as intellectual property to add to the IC's design.
Embedded Debugging may be performed at different levels, depending on the facilities available, ranging from assembly- or source-level debugging with an in-circuit emulator, to output from serial debug ports, to an emulated environment running on a personal computer.

 Embedded system - Facts, Information, and Encyclopedia Reference article
For embedded systems that are not high volume personal computers can often be conscripted into service either by limiting the programs or by replacing the operating system with a real-time operating system.
In addition, the embedded system may be outside the reach of humans (down an oil well borehole, launched into outer space, etc.), so the embedded system must be able to restart itself even if catastrophic data corruption has taken place.
These systems often have no operating system, or a specialized embedded operating system (often a real-time operating system), or the programmer is assigned to port one of these to the new system.

 Challenges in Embedded Database System Administration   (Site not responding. Last check: 2007-10-22)
As an embedded system is most often dedicated to a single application or small set of tasks, the operating conditions of the system are typically better understood than those of general purpose computing environments.
As embedded systems define a specific environment and set of tasks, requiring expertise during the initial system configuration process is acceptable, and we focus our efforts on the ongoing maintenance of the system.
As embedded systems typically perform fairly simple queries, such metrics are not nearly as relevant for embedded database systems as are ease of maintenance, robustness, and small footprint.

 Embedded Systems - Wikibooks, collection of open-content textbooks
It is important to realize that embedded systems rarely have display capabilities, and if they do have displays, they are usually limited to small text-only LCD displays.
The challenge of programming an embedded system then is that it is difficult to get real-time feedback from the system without a display.
Also, embedded systems usually have very strict memory limitations, processor limitations, and speed limitations that must play a factor in designing an embedded system, and programming an embedded computer.

 Testing embedded systems: Do you have the GuTs for it?
A real-time system is one in which the correctness of a computation not only depends on its logical correctness, but also on the time at which the result is produced.
Embedded systems are complex systems that can be composed of extremely diverse architectures ranging from tiny 8-bit micro-controllers up to large distributed systems made of multi-processor platforms.
However, two-thirds of these systems run on a real-time operating system (RTOS), either commercial off-the-shelf or in-house, and implement the concept of threads (a thread is a granule with an independent flow of control) that extend to the RTOS task or process.
