Real-time programming platforms in the mainstream environments

The functionality of a real-time system is divided into separate run able entities, referred to as tasks. The term real -time system refers to generally-rendered system as processing unit having a set of input & output. There exists a group of notions closely intertwined when speaking of real-time system. The term embedded system refers to equipment or devices not classified as standalone general-purpose computer architectures but whose functionality resembles that of dedicated computer architectures. while stand alone generalpurpose computer architectures designed to run a commonly used set of application, there is large diversity of embedded system architectures, where as essentially one general-purpose computer architectures. In this paper, a description of existing mainstream general-purpose real-time programming platforms is presented.
