4 bit alu using microprocessor
The Arithmetic Logic Unit designed performs the functions like addition,subtraction,division, AND,OR,NOT operations. The user can enter any value he wants and will get the desired result after the required operation. It consists of an MPS 85-3 microprocessor kit,seven segment display, 7448 IC. These together make our ALU. The program for the various operations is entered through the kit. The kit is then interfaced with the 7448 IC which is linked with the seven segment display.
