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 design of 32bit unsigned multiplier using CLAA and 32bit unsigned multiplier using CSLA multiplies and gives the product term of 64bit. The CLAA based multiplier and CSLA based multiplier uses the same delay for multiplication operation. These two 32-bit unsigned multipliers are simulated using Modelsim10.1b and synthesized using Xilinx14.2.
