Hi Bhupendra,
Vedic multiplier has a great importance in data path computation. You can check some recent papers, where it has been verified by simulation that efficient Vedic multiplier architecture supersedes Booth's multiplier, a renowned multiplication algorithm. Therefore, if you can design an efficient architecture for Vedic multiplier, it"ll be a great help for signal processing systems involving multiplication computation.
Good luck !

Multiplication is an important fundamental function in arithmetic operations. Multiplication-based operations such as Multiply and Accumulate(MAC) and inner product are among some of the frequently used computation Intensive Arithmetic Functions(CIAF) currently implemented in many Digital Signal Processing (DSP) applications such as convolution, Fast Fourier Transform(FFT), filtering and in microprocessors m its arithmetic and logic unit. Since multiplication dominates the execution tune of most DSP algorithms, so there is a need of high speed multiplier. Currently, multiplication time is still the dominant factor in determining the instruction cycle time of a DSP chip. The demand for high speed processing has been increasing as a result of expanding computer and signal processing applications. Higher throughput arithmetic operations are important to achieve the desired performance in many real-time signal and image processing applications . One of the key arithmetic operations in such applications is multiplication and the development of fast multiplier circuit has been a subject of interest over decades. Multiplier based on Vedic Mathematics is one of the fast and low power multiplier. Employing this technique in the computation algorithms will reduce the complexity, execution time, power etc. This vedic based multiplier is compared with binary multiplier(partial products method)
In vedic Times when no calculators were present to calculate the long data values, the guru's will use some methods for that type of calculation, now it is known as Vedic calculation. these methods are fast and very logical.
As we know that in today's digital world multipliers are the primary components so if we use vedic method of multiplication then the circuit delay time will reduce and it is also proved through many publications. Vedic Multipliers/ multiplication makes the digital execution very fast as compared to simple multiplication (for complex multiplications only)
Multiplication play a major role in many signal processing applications.
To increase speed of the signal processing architecture/unit, need to reduce computation time of the multiplication unit. The vedic mathematics based multiplication produce result fast manner compare to conventional multiplication process.
