Abstract	Real time task for which timing must be guaranteed is most important requirement in biomedical measurement systems. If the system fails to meet the deadline it can end up with severe error for the measurement purpose. In this paper to guarantee the response time of the biomedical data acquisition system hard real-time Linux operating system is proposed. The system is implemented both in Red Hat Linux and in windows. Experimental results shows that the processing time of a real time task is reduced to 10% than that of non real time windows and the time required for executing emergency job is 469 microseconds in the worst case. In our previous work [1,2] shows that the real time error (jitter) reduced the response time significantly under hard real-time (RT) Linux over other soft real time operating system(OS). In addition to this, the research given in this paper aims to analyze time delay introduced by hardware and software in the communication between pc and the data acquisition system by offering minimum delay with open source RT-Linux solution.
