Analysis of an Efficient Fault Tolerant Linear Feedback Shift Register for Low Power Applications

Traditional fault-tolerant Linear Feedback Shift Registers have historically been plagued by a significant vulnerability: numerous Single-Point-of-Failures (SPoFs), where a single fault could potentially compromise the entire system's functionality. Recognizing this critical limitation, researchers have developed an innovative solution called the Fault Tolerant-Linear Feedback Shift Register (FT-LFSR), which dramatically reduces the number of potential failure points. This breakthrough approach leverages a modified version of Triple Modular Redundancy (TMR), a well-established fault tolerance technique based on spatial redundancy.
