In the paper design of 64 bit ALU is presented. Arithmetic Logical Unit is the part of Microprocessor. All the arithmetic & logical functions are performed inside the ALU. So, ALU is the heart of the microprocessor. The speed of the ALU decides the speed of the microprocessor. Processor is the brain of the computer. Now ALU is the heart of the processor. In the designing of superscalar processors Fetch, Decode, Execute & Write back stages are present. Now ALU is the building block of the Execute stage. Now to execute the instruction operation code & the operand (digital data) is required. Now the Opcode is transferred by control unit tell the processor which operation is done at which time.
