This paper presents a method for double precision floating-point comparators that processes three numbers at once. For many scientific and computing applications that depend on precise statistical comparisons, these capabilities are essential. Complex numerical comparisons are made possible by the requirement to process three numbers at once, which also makes mathematical processing simpler. Using sophisticated High-Level Synthesis (HLS) tools such as Vitis HLS and Vivado, our methodology achieves a simulation time of 6.287 ns. This highlights the remarkable potential of High-Level Synthesis tools in creating computing components.
