Higher component density, lower voltage levels and higher transistor counts increase programmable systems' susceptibility to transient faults. At the same time, the adoption of embedded systems in many safety-critical and mission-critical systems makes their reliability of utmost importance. Softwareimplemented error detection techniques can be utilized to protect these systems as an alternative to less flexible and costlier hardware solutions like redundant hardware or fully duplicated systems. One of these techniques is the low-level re-executionbased technique called DETECTOR, which matches the error reduction capabilities of other state-of-the-art techniques while utilizing only three reserved CPU registers. This is in contrast to other techniques, which required a large number of CPU registers to be reserved, making them unusable for some programs. This paper provides an optimization of DETECTOR by combining parity checking with DETECTOR's re-execution mechanism. The technique, called P-DETECTOR, is validated extensively on multiple data processing and I/O-driven case studies and compared to the state-of-the-art. The results show that, compared to an unprotected system, the P-DETECTOR technique reduces the percentage of faults resulting in a corrupted output by 93.76% for control flow errors and by 87.89% for data flow errors, outperforming DETECTOR and matching other state-ofthe-art techniques like RACFED, SWIFT and FDSC.

“…the code implementing DETECTOR. The software implemented fault injection (SWIFI) processes that were used for the data processing case studies and for the industrial case study have previously been described in [38] and [39], respectively. They both involve repeatedly selecting an instruction, executing the target program until that instruction, injecting a fault at that position, and resuming the execution.…”

Nowadays, embedded systems are widely used both in general-purpose as well as in safety-critical applications. Due to technological advances, these embedded systems can operate on extremely small footprints and low voltages. This, however, makes them more susceptible to external disturbances such as electromagnetic interference. These disturbances can cause single event upsets, a bit being flipped inside the microcontroller, which in turn can result in unexpected and unpredictable behavior of the system due to control flow errors or data flow errors. Many software-implemented control flow and data flow error detection techniques have been examined in the past. However, these techniques often require a large amount of devoted CPU registers to work correctly. Not every system is able to devote a large portion of its registers to an error detection technique. This paper proposes DETECTOR: a new low-level re-execution based technique protecting against both data flow and control flow errors, while using only three CPU registers. The experimental results presented in this paper are promising, showing that DETECTOR is able to significantly increase the reliability of the system.
