Abstract: Ensuring the seamless operation of modem digital systems requires a delicate balance between computational performance, fault tolerance, and resource efficiency. Conventional methods for achieving reliability, such as Triple Modular Redundancy (TMR), impose substantial area and power penalties, while more efficient alternatives like Reduced Precision Redundancy (RPR) often sacrifice accuracy and employ complex voter logic. This project introduces an Improvised High Precision Redundancy Multiplier (HPR-Mul) that resolves this trade-off by integrating a high-speed Fast Bipartitioned Hybrid Adder (FBHA). The HPR architecture uniquely combines one full-precision multiplier with two reduced-precision replicas, · cleverly reusing intermediate signals from the primary unit to enhance the accuracy of the redundant calculations. This technique enables· the use of a simple, robust voter, overcoming a key limitation of RPR systems. The principal innovation is the strategic replacement of the conventional final adder with the FBHA, which significantly shortens the critical path delay. Simulation and synthesis results confirm that the proposed design achieves a 21.67% reduction in delay and uses 4.3% fewer slices than the baseline HPR model, all while maintaining high fault tolerance. This makes the FBH-HPR multiplier a highly effective and scalable solution for safety-critical and high-performance applications, including digital signal processing and neural network acceleration.
