EMBEDDED SYSTEM
ABSTRACT These papers give a simple and precise introduction about Embedded System with a brief knowledge about the processor software (here C++) used in embedded system. One of the most important applications of the Embedded System used for Security by the use of Smart Card is also explained. Through these papers, a small attempt is made to highlight the importance of the Embedded System.
Embedded system is one of the emerging technology nowadays. In the design of embedded system RTOS, electronic and hardware implementation is carried out. It has its various applications like in medical field, control systems, device drivers, electronic consumer devices etc. Hence, embedded system can lead towards more automated and convenient life.
Today almost every electronic device contains embedded software in it. There is software hidden away inside our watches, microwaves, VCRs, cellular phones and pagers; the military uses embedded software to guide smart missiles and detect enemy aircraft; communication satellites and space probes would be nearly impossible without it. Each embedded system is unique and highly customized to the application at hand. As a result, embedded system programming is a widely varying field that can take years to master.
Most embedded systems are small enough to sit on the end of your thumb and are usually hidden within much larger and more complex mobile computing or electronic devices, so they often go unnoticed. But embedded systems actually represent the vast majority of semiconductor sales. According to the World Semiconductor Trade Statistics blue book, there are an estimated 5 billion embedded microprocessors in use today - a whopping 94 percent share of the world market. (By comparison, unit sales of high-profile PC processors, such as the Intel Pentium and Motorola PowerPC, check in at only 6 percent market share.)
