An embedded computer is essentially a small computer system-a set of computer components that have a dedicated internal function but are not part of the overall computer system itself. Embedded systems are used in mobile phones, digital cameras, medical imaging devices, handheld computers, PDA's and other similar consumer electronics. In the past, embedded systems were somewhat larger than traditional computers and relied on a microprocessor. However, with the increase in size and speed of modern computers and the associated applications, embedded systems have become smaller and more powerful. Today they can fit into the palm of your hand.
The cost of embedded computers and their components has been steadily decreasing over the last several years due to improvements in manufacturing techniques, cost reduction measures by manufacturers, and the increased availability of skilled IT labor. However, many consumers are still concerned about buying embedded computers and their corresponding software. Why is this? Because embedded computers have many different components and are typically more difficult to program for than a stand-alone PC. However, consumers can get around this by purchasing a software CD that has preinstalled components that make it much easier to program and use.
Embedded computer systems run on low-powered processors which make them very energy efficient. As a result, many embedded computers are capable of operating on batteries such as those found in digital cameras, cell phones, iPods, laptops, watches, calculators, televisions, and compact fluorescent bulbs. This fact also makes them a popular choice for use in rugged applications, high-tech office equipment, military operations, and industrial facilities.
Embedded computers do not have memory or permanent storage capacity built into their CPU design. Instead, these systems use dynamic memory modules and permanently fixed computer circuit boards. This enables these devices to work on memory alone while leaving all other system components free to execute their respective tasks. Therefore, they conserve power by not needing an idle PC for hours upon hours at a time. For applications requiring a lot of memory and continuous access to I/O data, however, this power efficiency factor does not translate into price savings. In order for an embedded computer to deliver low power consumption at the greatest level of efficiency, its components must be functioning well and must be thoroughly tested.
Embedded computers usually come with several different software packages. These allow these devices to perform a variety of tasks, including data processing, data encoding, sound processing, networking, and image processing. In addition, embedded devices come with their own unique I/O subsystems and application software suites. These allow these devices to process information coming from different sources, such as input devices, digital media, video, audio, or physical stimuli, in order to deliver the results that consumers demand.
Embedded systems allow a smaller footprint on a desktop or laptop. Due to their small size, these devices are more portable and can be used in a number of different environments. A larger system can also take up more desk space, but most embedded systems come with a compact design and are very easy to move around and store. Because they are more compact and have fewer moving parts, embedded systems are more durable than their larger counterparts. These small units can also provide a better performing and output than a large computer system, especially if there are fewer peripheral controls and inputs. Explore Premio embedded computers!
