DESIGN AND IMPLEMENTATION OF 8 BIT ALU USING VHDL TOOL

 

AIM:

                  The aim of the project is to design an 8 Bit ALU using VHDL software tools and implement it in programmable IC PAL/FPGA.

 

THEORY:

                 The ALU is a device that can be used to perform Arithmetic and Logical operations on the binary data. The proposed device can accept two numbers of 8 bit binary data and can perform logical/arithmetic operation depending on the control signal. It is proposed to give 4-bit binary controlled signal and so eight different operations areperformed.

 

HARDWARE:

                  The Hardware of 8 bit ALU consists of PAL C22V10/FPGA as 8 bit ALU, buffer, SPDT Switch and LEDs.

SOFTWARE:

                Using VHDL software tool, a digital system can be designed and simulated. Also the Timings of various signals can be verified. Then the system can be implemented in PAL C22V10 using WARP-R4 or can implemented in ALTERA/ATMEL FPGA using MAX plus II/IDS 6.0.

 

APPLICATIONS:

               The ALU can be mainly used in

Ø     Microprocessor

Ø     Microcontroller
