TMRs
TMRs, or Triple Modular Redundancy systems, are a type of fault-tolerant computing technique used to improve the reliability of electronic systems. The concept behind TMRs is to replicate critical components of a system three times, creating three identical modules that perform the same function. These modules operate in parallel, and their outputs are compared continuously. If one of the modules fails or produces an incorrect output, the other two modules' outputs are used to determine the correct result. This redundancy ensures that the system can continue to function correctly even if one of the modules fails, thus enhancing the overall reliability and fault tolerance of the system. TMRs are commonly used in applications where high reliability is crucial, such as aerospace, automotive, and medical devices. The technique can be applied at various levels of a system, including hardware, software, and even entire subsystems. However, it is important to note that while TMRs significantly improve reliability, they also increase the complexity and cost of the system due to the need for additional hardware and the overhead of managing multiple modules.
