Real-time issues in embedded system design

Abstract

The Embedded system is controlled with the combination of hardware and software. They are usually processed by a microprocessor / microcontroller that execute instructions which are present in ROM. The term "embedded" reflects to the fact that they are part of the system. Real-Time Operating System (RTOS) combines with two thoughts "real-time" and "operating system". These are the operating system where the performance is based on the logical result and the time at which the results are obtained. The operating system called as RTOS running real time applications provide the result of course in the required time frame. The working procedure is almost the same as normal operating system, but also offers to allow the real time scheduling tasks. The RTOS is not going to increase the speed of execution, but it is accurate than the general OS.
