TMR Operation

• In voting systems, a crucial process involves voting on input data and using the voted result in the subsequent calculation pass. This sequence of operations occurs within a fixed time interval known as the frame, ensuring a consistent and uniform rate of operation for the control program.
• For SIFT systems, a substantial portion of fault tolerance is achieved through software implementation. The advantage of this approach is that software does not degrade over time, ensuring the system's long-term reliability. The SIFT design relies on three identical controllers with provisions for data transfer between them. Through software, data exchange, voting, and output selection can be efficiently executed.
• While most aspects of the system utilize software solutions, hardware output circuitry requires modification for hardware voting. This integration ensures robust fault tolerance and enhances the overall system's reliability.
• Each controller in the SIFT system employs identical software, allowing for synchronization and response to an identical copy of itself operating in the other controllers. This coordination is achieved through a distributed executive, composed of the three synchronized programs. The distributed executive efficiently manages all controller operations, including the input, vote, calculate, and output sequences mentioned earlier.
• Through this sophisticated approach, the SIFT system achieves a high level of fault tolerance, ensuring consistent and accurate data processing. The distributed executive's synchronized control ensures smooth and coordinated operation across all controllers, providing a reliable and effective voting system for critical applications.
