Abstract :

The 64-bit Signed/Unsigned Multiplier presents a Very high speed integrated circuit – Hardware Description Language (VHDL) based design and implementation of a fast unsigned multiplier. Booths multiplication algorithm is a multiplication algorithm which is used to perform multiplication function for two signed binary numbers in twos complement notation. The algorithm was invented by Andrew Donald Booth in 1950 while doing research on crystallography at Birkbeck College in Bloomsbury, London. Booth algorithm used desk calculators that were faster at shifting than adding and created the algorithm to increase their speed. The multiplier uses a carry look ahead adder, which reduces the delay time caused by the effect of carry propagation through all the stages of a -carry adder. The main focus is on the enhancing the speed and complexity of the 64 bit Signed/Unsigned multiplier and it also provides a performance comparison between the fast multiplier and a ripple-carry adder based multiplier.
