Enhancing CuFP Library with Self-Alignment Technique
Hajizadeh, Fahimeh; Ould-Bachir, Tarek; David, JP
High-Level Synthesis (HLS) tools have transformed FPGA development by streamlining digital design and enhancing efficiency. Meanwhile, advancements in semiconductor technology now support the integration of hundreds of floating-point units on a single chip, enabling more resource-intensive computations. CuFP, an HLS library, facilitates the creation of customized floating-point operators with configurable exponent and mantissa bit widths, providing greater flexibility and resource efficiency. This paper introduces the integration of the self-alignment technique (SAT) into the CuFP library, extending its capability for customized addition-related floating-point operations with enhanced precision and resource utilization. Our findings demonstrate that incorporating SAT into CuFP enables the efficient FPGA deployment of complex floating-point operators, achieving significant reductions in computational latency and improved resource efficiency. Specifically, for a vector size of 64, CuFPSAF reduces execution cycles by 29.4% compared to CuFP and by 81.5% compared to vendor IP while maintaining the same DSP utilization as CuFP and reducing it by 59.7% compared to vendor IP. These results highlight the efficiency of SAT in FPGA-based floating-point computations.
