The last one I have designed was in I remember there are extra 2 bits used for sign extension of the Partial Products and I thought that was the major drawback of the modified booth algorithm. Can you refer a paper Has to be after I'm sure there are a lot of improvements done in 6 years.

For arithmetic multiplication various Vedic multiplication techniques like Urdhva tiryakbhyam, Nikhilam and Anurupye has been thoroughly discussed. It has been found that Urdhva tiryakbhyam Sutra is most efficient Sutra Algorithmgiving minimum delay for multiplication of all types of numbers, either small or large.
Finally, the implemented design has been tested by using Built in Self Test, which shows that this Vedic multiplier is completely fault free.

Implementation of vedic multiplier using BIST…………………………………. Title of Table Page No. Summary of FPGA features……………………………………………………………. Since multiplication dominates the execution time 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.
Reducing the time delay and power consumption are very essential requirements for many applications [2, 3]. This work presents different multiplier architectures.
Multiplier based on Vedic Mathematics is one of the fast and low power multiplier. Minimizing power consumption for digital systems involves optimization at all levels of the design. This optimization includes the technology used to implement the digital circuits, the circuit style and topology, the architecture for implementing the circuits and at the highest level the algorithms that are being implemented.
Digital multipliers are the most commonly used components in any digital circuit design. They are fast, reliable and efficient components that are utilized to implement any operation. Depending upon the arrangement of the components, there are different types of multipliers available.
Particular multiplier architecture is chosen based on the application. In many DSP algorithms, the multiplier lies in the critical delay path and ultimately determines the performance of algorithm.
The speed of multiplication operation is of great importance in DSP as well as in general processor. In the past multiplication was implemented generally with a sequence of addition, subtraction and 1 shift operations. There have been many algorithms proposals in literature to perform multiplication, each offering different advantages and having tradeoff in terms of speed, circuit complexity, area and power consumption.
The multiplier is a fairly large block of a computing system. The amount of circuitry involved is directly proportional to the square of its resolution i.
A multiplier of size n bits has n2 gates. For multiplication algorithms performed in DSP applications latency and throughput are the two major concerns from delay perspective.signed number) and the systolic array multiplication algorithm (for unsigned number).

High-speed multipliers are essential building blocks for modern computers, signal processing and other digital systems. A new parallel multiplier configuration is developed in this paper by using the signed digital number systems incorporated with the modified version of Booth's algorithm.
