FPGA based Multi-Precision Floating-Point MAC

Floating-Point Multiply-Accumulate (FPMAC) units are fundamental in high-performance computing applications such as digital signal processing and machine learning. This study presents an optimized FPGA-based FPMAC, integrating Booth encoding for multiplication, Wallace tree-based partial product reduction, and a 3:1 compressor for efficient accumulation. Comparative analysis highlights significant performance improvements over conventional designs, including a 30% reduction in delay, an operational frequency of 488 MHz, and a 22% increase in throughput. Additionally, power consumption is reduced by 55%, while resource utilization is optimized. The proposed architecture, with five pipeline stages, enhances computational efficiency, making it highly suitable for real-time embedded applications requiring high-speed floating-point operations.
