Embedded Systems
Embedded Systems evolved with general-purpose computer systems. They were at the forefront of the use and justification of computer products, the closest to the field. This is where the theories are making or breaking. In the past, most of the embedded research and development was identified with real-time systems and industrial settings, but things have been changing since. With wider deployment of computers, the need for Embedded Systems has increased. We can recognize this in almost any facet of our lives: Embedded Systems is in most house appliances, cars, electrical devices, and industrial devices and tools.
This seems to be a long-lasting trend in front of us, of the same or larger impact and disruption than the appearance of the Web. Being widespread poses some hard requirements on Embedded Systems. They must be as reliable and robust as other house appliances; as easy to use and as available; connected with other devices, requiring adherence to standards of some kind; and low cost— consequently their development will be defined on a strictly economical basis.
Downfalls of Embedded Systems
There are, however, several downfalls to embedded technology. When problems develop with a personal computer the manufacturers can develop and release a software patch to their customers, who can then rectify the problem themselves. Problems with Embedded Systems, however, are more difficult to fix. Embedded Systems is not designed for user interaction, so the majority of Embedded Systems are just that – embedded within the product, with no easy method of updating or repairing their software.
Since Embedded Systems are often used to control such functions as braking in an automobile or the guidance system on an intercontinental missile they cannot be released onto the market before they have been extensively tested and retested. Quite simply, there can be no margin of error. As a result the cost of Embedded Systems can often be deceptively high. While the manufacturing costs are reduced, the testing and quality control costs can be higher than expected.
