Abstract

Multiplication is one of the basic functions in all digital circuits. It is widely used in digital signal processing (DSP) applications. Hardware resources utilization and processing time required by it are more than addition and subtraction. There are two different kinds of multiplication algorithms known as, serial multiplication algorithms and parallel multiplication algorithm. Serial multiplication schemes are widely used in sequential circuits, it contain feedback loop. Parallel multiplication algorithms often used in combinational circuits, it does not contain feedback structures. This paper presents various multiplier architectures. Multiplier architectures generally classified into two categories, one is “tree” multipliers and another one is “array” multipliers. Tree multipliers add as many partial products in parallel as possible and therefore, are very high performance architectures. Multiplication operation involves generation of partial products and their accumulation. The speed of multiplication can be increased by reducing the number of partial products.
