ABSTRACT
Embedded Real Time application uses multi threading, a key concept of any conventional OS. The advantage of multithreading include greater throughput, more efficient use of CPU such that it cannot remain idle for long time, better system reliability, improved performance on multiprocessor computer. The use of Real Time Operating Systems (RTOSs) became an attractive solution to simplify the design of critical real-time embedded systems for safety constraints. Due to their demanding strict attention to rules and procedures,constraints such as highspeed, low voltage operation and battery-power dependence, because of sudden up and down of voltages, flow of current these systems are frequently causes transient faults. External conditions, such as Electromagnetic Interference (EMI), HeavyIon Radiation (HIR) as well as Power Supply Disturbances (PSD) can also cause transient faults. As the major consequence, the system’s reliability degrades.In this paper, the main focus will be on the monitoring the faults or detection of the faults on the serial communication lines that corrupts the execution flow of tasks in embedded systems based on preemptive RTOS. During execution of these programs, the proposed system was exposed to conduct EMI according to the international standard for voltage transients, voltage dips and short interruptions on the serial communication lines of electronic systems. The obtained result shows that the proposed approach is able to provide higher fault coverage.
