SYSTEM EVALUATION OF 32 BIT UNNSIGNED MULTIPLER USING CLAA AND CSLA
Main Article Content
Abstract
In this paper deals with the comparison of the VLSI design of the carry look-ahead adder (CLAA) based 32- bit signed and unsigned integer multiplier. Multiplication is a fundamental operation in most signal processing algorithms. Multipliers have large area, long latency and consume considerable power. Therefore low-power multiplier design has been an important part in low- power VLSI system design. In computational circuits the adders plays a key role in arithmetic operations. Adders like Ripple carry adder, Carry look ahead adder, Carry select adder, Carry skip adder and carry save adder etc. In this paper, a high performance and low power 32bit unsigned multiplier is proposed using adders. The CLAA based multiplier and CSLA based multiplier uses the same delay for multiplication operation.
