Implementation of parallel processing with tri-master and N-slaves is an idea to enhance the performance of computing in real-time. Usual schematics of parallel algorithm take more space and cost. But this model is a solution for that. In this paper, two master processors are used to organize the I/O operations & another one processor is a universal control for the system. Slaves are controlled by the sub-master processors & sub-master processors are controlled by universal master processor. This system consists of three operating systems.
