embedded operating system

An embedded operating system is an operating system for embedded computer systems. Embedded operating systems are computer systems designed to increase functionality and reliability for achieving a specific task. Depending on the method used for Computer multitasking, this type of operating system might be considered a real-time operating system (RTOS). All embedded systems contain a processor and software. There must be a place for embedded software to store the executable and temporary storage for run-time data processing. The main memory on an embedded system can be ROM and RAM. All embedded systems must also contain some form of input interface and output interface to function. The embedded hardware is usually unique and varies from application to application. Because the hardware running the embedded operating system can be very limited in resources, the embedded design of these operating systems may have a narrow in scope tailored to a specific application, so as to achieve the desired operation under the given hardware constraints. The embedded operating system that organizes and controls the hardware usually determines which other embedded hardware is needed. To take better advantage of the processing power of the Central processing unit (CPU), software developers may write critical code directly in assembly language. This machine efficient language can potentially result in gains in speed on deterministic systems at the cost of portability and maintainability. Often, embedded operating systems are written entirely in portable languages, such as C. Operating systems on typical embedded systems
