In this paper, we are designing and implementing the 8 bit Microprocessor using VHDL synthesis tool Xilinx
14.2 on FPGA board. Microprocessor is basically an electronic device which consists of ALU and Control circuitry
which is required to work as computer’s CPU. The Control unit is the main part of this design, which controls all
modules which performs different operations like Arithmetic and Logical operations. Each and every module is designed
separately and after that control unit combines these entire module using control signals. Our system was implemented
on the Xilinx Spartan 3 XC3S400PQ208 using ISE foundation 14.2 and VHDL. Total 329 slices, 415 slice flip-flops, 320
four inputs LUTs, 38 numbers of Bounded IOBs are used.
