Main purpose of this report is to analysis Design and Implementation of 2 Bit ALU Using Logic Unit. Here ALU is an arithmetic logic unit use as multi-operation, combinational-logic digital function. This 2-bit ALU has been designed based on 8 arithmetic operations and four logic operations. Analysis focus on reduce the time delay so this 2-bit ALU by using the latest version of Pspice software where the full-adder is also designed by logic gate.
