Abstract	Real time operating systems and embedded systems are increasingly using in the development of projects of industrial automation divided in several areas of research such as, for example, robotics, telecommunications, and industrial bus. These applications on modern control systems need, very high reliability, speed communication, besides temporal determinism. Real time operating systems (RTOS) has been presented as a reliable solution when applied on systems that are based in real time requirements, further on computing performance is totally dependent of the operating capacity processing unit. On monoprocessing system a portion of the computing capacity, of the processing unit, it is used in management activities such as, for example, processes of context switching, and context sefety. In consequence of this, it arise the computing overload a significant characteristic for the performance system. This work has for objective to analyze and to provide an alternative architecture, especially developed to accomplish the co-processing of tasks on platform IBMPC, increasingly computing capacity of main processor. In the present research, the coprocessing platform accomplishes the execution of algorithm scheduling on system, this way the task’s management was distributed between the platform IBM-PC and co-processing unit.
