As cost-optimized FPGAs are usually considered in this scope that contain only a small number of DSPs, the excessive use of multipliers quickly exceeds the available fabric resources. To overcome this drawback, Sets-Of-Real-Numbers (SORNs) are taken into account, which generally leads to a significant reduction of complexity at the cost of precision impairments. For evaluation, cross-correlation hardware architecture is implemented in VHDL considering SORN-based multipliers into account and compared to standard fixed-point. The results show a reduction in complexity for LUTs of up to 46 %, highlighting our approach as a feasible solution for resource-constrained systems.enTechnology::600: TechnologyConference Paper10.1109/mocast65744.2025.11083906Conference Paper
