“…RNS multiplication [11] uses a combination of LUT's and arithmetic units keeping in mind the balance between speed and hardware complexity. Multiplication has been done using an AND gate array, some LUT's and using a multistage carry save adder known as the Wallace Tree Multiplier.…”

This paper presents a comparative study of the performances of arithmetic units, based on different number systems like Residue Number System (RNS), Double Base Number System (DBNS), Triple Base Number System (TBNS) and Mixed Number System (MNS) for DSP applications. The performance analysis is carried out in terms of the hardware utilization, timing complexity and efficiency. The arithmetic units based on these number systems were employed in designing various modulation schemes like Binary Frequency Shift Keying (BFSK) modulator/demodulator. The analysis of the performance of the proposed modulator on above mentioned number systems indicates the superiority of other number systems over binary number system.
