ABSTRACT: 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.
