1.3 The Future of Embedded Systems
Until the early 1990s, embedded systems were generally simple, autonomous devices with long product lifecycles. In recent years, however, the embedded industry has experienced dramatic transformation, as reported by the Gartner Group, an independent research and advisory firm, as well as by other sources:
· Product market windows now dictate feverish six- to nine-month turnaround cycles.
· Globalization is redefining market opportunities and expanding application space.
· Connectivity is now a requirement rather than a bonus in both wired and emerging wireless technologies.
· Electronics-based products are more complex.
· Interconnecting embedded systems are yielding new applications that are dependent on networking infrastructures.
· The processing power of microprocessors is increasing at a rate predicted by Moore’s Law, which states that the number of transistors per integrated circuit doubles every 18 months.
If past trends give any indication of the future, then as technology evolves, embedded software will continue to proliferate into new applications and lead to smarter classes of products. With an ever-expanding marketplace fortified by growing consumer demand for devices that can virtually run themselves as well as the seemingly limitless opportunities created by the Internet, embedded systems will continue to reshape the world for years to come.
