ABSTRACT
In this paper VHDL implementation of complex number multiplier using ancient Vedic mathematics and conventional modified Booth algorithm is presented and compared. The idea for designing the multiplier unit is adopted from ancient Indian mathematics "Vedas". The Urdhva Tiryakbhyam sutra (method) was selected for implementation since it is applicable to all cases of multiplication. Multiplication using Urdhva Tiryakbhyam sutra is performed by vertically and crosswise. The feature of this method is any multi-bit multiplication can be reduced down to single bit multiplication and addition. On account of these formulas, the partial products and sums are generated in one step which reduces the carry propagation from LSB to MSB. The implementation of the Vedic mathematics and their application to the complex multiplier ensure substantial reduction of propagation delay. The simulation results for 4 bit multiplication using Booth’s algorithm and using Vedic sutra are illustrated. the methods required to implement a high speed and high performance parallel complex number multiplier. The designs are structured using radix-4 modified Booth algorithm and Wallace tree. These two techniques are employed to speed up the multiplication process as their capability to reduce partial products generation to eta/2 and compress partial product term by a ratio of 3:2. Despite that, carry save-adders (CSA) is used to enhance the speed of addition process for the system. The system has been designed efficiently using VHDL codes for 16 times16-bit signed numbers and successfully simulated and synthesized using ModelSim XE II 5.8c and Xilinx ISE 6.1i. As a proof of concept, the system is implemented on Xilinx Virtex-II Pro FPGA board.

INTRODUCTION
Multipliers are key components of many high performance systems such as FIR filters, microprocessor, digital signal processor, etc. A systems performance is generally determined by the performance of the multiplier, since the multiplier is generally the slowest element in the system [2]. Complex number operations are the backbone of many digital signal processing algorithms which mostly depend on extensive number of multiplication. Complex number multiplication involves four real number multiplication and two additions/ subtractions . While doing real number multiplication, carry needs to be propagated from the least significant bit (LSB) to most significant bit (MSB) when
binary partial products are added. The overall speed is drop down by the addition and subtraction after binary multiplication.Vedic Mathematics is an ancient mathematics which is based on 16-sutras and 16-sub sutras invented by Jagadguru Shankaracharya Bharati Krishna Teerthaji Maharaja (1884-1960). Mainly multiplication in Vedic mathematics in carried out using three sutras Nikhilam Navatascaraman Dasatah, Ekadhikena Purvena and Urdhva Tiryakbhyam . Urdhva Tiryakbhyam sutra is the targeted Vedic sutra (algorithm) as it is suitable for all cases of multiplication. The most common multiplication algorithms used are Array multiplication and Booths algorithm. The computational time in case of Array multipliers are comparatively less since the partial results are calculated in parallel. Multiplication using Booths algorithms takes comparable computational time . These algorithms are used for multi-bit and exponential operations that require large partial results and carry registers . This paper presents multiplication algorithm that may be useful in the efficient implementation of signal processing algorithms. The framework of this multiplication algorithm is based on Urdhva Tiryakbhyam sutra of Vedic mathematics. This paper is organized as follows. In section II the implementation methodology of complex number
multiplication using Booth-Wallace algorithm, Urdhva Tiryakbhyam sutra of Vedic mathematics is explained with examples. Device utilization in both is compared and discussed in Section III. Results obtained for 4-bit complex multiplication are presented in section IV. Concluding remarks are presented in section V.
