Embedded technology has changed the way we live and use our gadgets. An embedded system is a computer system designed to perform dedicated functions. Embedded systems are the norm rather than the exception for almost all electronics devices. Embedded technology is found in a range from portable devices, stationary installations like traffic light controllers, programmable logic controllers, and large complex systems like hybrid vehicles, medical imaging systems, and avionics.
Embedded system typically controls physical operations of the machine that it is embedded within. Ninety-eight percent of all microprocessors manufactured are used in embedded systems. Embedded control systems and in particular microcontrollers are used in virtually every electronic system. Lots of consumer electronics have embedded CPU and thus became embedded systems. For example, PDAs, cellphones, point-of-sale devices, VCRs, industrial robot control, or even your toasters can be embedded system.
There is more and more demand on the embedded system market. Some reports
suggest that the demand for embedded CPUs is
10 times as large as general purpose PC CPUs. Embedded systems control many
devices that are in common use today. Ninety-eight percent of all
microprocessors manufactured are used in embedded systems.
Modern embedded systems or
embedded technology based on microcontrollers. A common standard class of
dedicated processors is the digital signal processor. Embedded technology is
used in dedicated specific tasks, design engineers can optimize it to reduce the
size and cost of the product and increase the reliability and performance.
Embedded technology products are mass-produced, benefiting from economies of
scale.
