Embedded software is built in your electronics and can be found in various appliances. This kind of software is being popularly used in missiles, airplanes, process control systems too. This software is developed on a broad range of embedded processor. These processors comprise of 8, 16 and can come in 32 bits too. It works on RTOS which is Real-time Operation Systems.
These systems require one or more Main Processing cores in order to control them. These processing cores which are used to control include micro controllers and digital signal processors or DSP. In order to carry out some of the specialised task you may need processors which are really powerful. In case of an airplane, we need an embedded system to control the air traffic as it is a specialised task. In addition to a powerful processor you also need dedicated national and regional networks along with a main frame computer. These networks both national and regional are connected between radar sites and the actual airport. Embedded systems become indispensable in these radars and may some times require more than one of these systems.
This software has been a boon to Telecommunications industry, specially mobile communications. Today, it has been part and parcel of modern life tasks which includes the use of mobile phones and its software. Traffic control, factory control, air traffic control and is also used in telephone switches. In order to route data, they make use of network bridges and routers along with computer network. Of late, its usage has been found in MP3players, DVD players, digi Cameras and advanced video games. Electronic gadgets such as PDAs, as we all know it ‘the Personal Digital Assistants’.
