  • [Slide Objective: Articulate the current and future market trends that will be driving the business of OEM system developers in the new decade] The embedded marketplace is undergoing fundamental change as market trends such as ever-increasing customer demands, new technologies, and the ongoing evolution of the technology industry offer challenges and opportunities to the embedded system developer. 1) Customer Demands are Changing: Customers are increasing asking their devices to do more, cost less, and connect with everything. Customers want richer functionality that include some of the latest desktop and server features to provide richer applications and services. They want lower cost, not only in terms of the device cost they pay but the ongoing support costs to manage and update the device more easily and centrally. Finally they are looking for greater interoperability and connectivity to access and exchange information with their existing and evolving IT infrastructure and other computing systems 2) The Technology Industry continues to evolve The second major embedded industry trend is the influence of the larger ongoing computer industry trends as hardware and bandwidth costs continue to fall at 30-50% per year. In addition, increasing standardization and time-to-market pressures encourage the greater use of commodity off-the-shelf hardware, open communication standards and commercial rather than proprietary embedded operating systems. 3) Because of these customer and industry changes, New Technologies continue to enter the embedded marketplace as their use becomes more popular, possible, and affordable Technologies like: Increasingly TCP/IP centric communication options Richer GDI/GUI for user interactivity Availability of Distributed computing through object-oriented application technologies Methods to integrate with databases, mail servers, and web servers Configurable Internet browsing Remote Device Manageability The combination of these market trends result in escalating demands for more features, delivered more quickly to the marketplace at lower and lower costs. Moreover, this trend will only accelerate further as 32-bit computing and standardized pervasive connectivity become more standard.

    3. 3. Who am I anyway? <ul><li>Name : Ch.Vishwa Mohan </li></ul><ul><li>Qualification : M.E ( Inst ) passed in 1994. </li></ul><ul><li>Experience : Over 15+ Years of Software development experience specially in Embedded/ Real Time systems in Industrial Automation, Process Control, Semi conductor related areas. </li></ul>
    4. 4. What is an Embedded System ? <ul><li>Any electronic device that incorporates a Microporcessor within its implementation is called an Embedded System . </li></ul><ul><li>An embedded system is a computer-controlled system. The core of any embedded system is a Microprocessor , programmed to perform a few tasks (often just one task). </li></ul><ul><li>A combination of computer hardware and software , and perhaps additional mechanical or other parts, designed to perform a dedicated function. </li></ul><ul><li>A specialized computer system which is dedicated to a specific task </li></ul>Slide
    5. 5. History of Embedded Systems <ul><li>The first mass-produced embedded system was the guidance computer for the Minuteman missile in 1961. It was the Autonetics D-17 guidance computer, </li></ul><ul><li>In 1960’s the first consumer-oriented microprocessor was Intel 4004. ( Which used in calculators and small systems.) </li></ul><ul><li>In 1970’s 8 bit microprocessor was norm. but in general still required external memory chips, and decoding logic, as well as any interfaces to the external world. </li></ul><ul><li>In mid 1980’s higher level of integration meant that most of the previously external systems components moved onto the same chip as the processo4r. Such integrated systems were called microcontrollers. </li></ul><ul><li>By the end of 1980’s embedded system were the norm rather then the exception for almost all electronic devices this trend has continued since. </li></ul>Slide
