In our daily lives, embedded systems have become an essential part of our lives. It can bea mobile phone, a smartcard, a music player, a router or any other electronic device that israpidly changing our lives. An embedded system is defined as a group of several devicesor parts, such as computer software, hardware, and extra mechanical components, intendedto accomplish a specific function on the fly on a time-based basis. For that, the real-timeoperating system (RTOS) becomes the foundation of embedded systems 1. These RTOSsare lacking in memory and processing power. For this reason, memory management isessential and has been a topic of research since the inception of RTOSs. An RTOS is a typeof operating system that supports real-time applications by providing an accurate resultwithin a specified time frame. This time duration is called the "deadline".
