“…Virtual integration involves integration between software components, and instances. To support this different software architecture, software platforms (RTOS) are used to provide partition mechanism, hardware resource management like CPU, Memory, input-output, interface between functionalities, communication mechanism, protocols between software components, networking methods using network stacks and concepts like TCP/IP protocol (Kinnan, Larry M. 2007). The virtual integration comes under the Product Systems Engineering (PSE), which focusses on the design, development and enhancement using RTOS, which plays a very important role in implementing system engineering principles like considering budget and schedule constraints, phase by phase development, model based development, easy to test, easy to integrate, easy to add new features, easy to modify architecture etc.…”
