Embedded systems: technology for the future
Embedded systems is the technology of today and the future. The advent of embedded systems was a remarkable feat in terms of hardware and software. Since then there has been a tremendous evolution in hardware technologies in the form of microprocessors, programmable silicon chips, debugging tools and so on. In parallel, a substantial amount of research has gone in to the understanding of control systems.
Consequently, there has been a quantum leap in design principles of Embedded Systems with almost every thing in the world switching from analog to digital solutions. They increase the work capability and power of the appliances. They also provide extra capabilities for them.
"An embedded system is a special-purpose computer system usually built into a smaller device."
The term embedded system is a nebulous one that encompasses just about everything except desktop PCs. An embedded system is one that is preprogrammed to perform a dedicated or narrow range of functions as part of a larger system, usually with minimal end-user or operator intervention.
These embedded systems are dedicated to a particular application. These applications may require manipulation of platforms to meet real time performances. The hardware required varies with the environment and may need application specific components, specialized processors, and multiprocessor and/or distributed architectures. The construction for all the embedded systems is almost the same though they are of different types. An embedded system consists of processor, memory, and software.
Normally, any computer works only if there is an operating system. Even in case of embedded systems, we use an operating system, which are bit different from the regular operating system. The operating systems used in embedded systems are generally called Real Time Operating Systems (RTOS).
