OBJECTIVE

The first and foremost reason to work on this project is to understand the underlying

concepts of VlSI Designing and FPGA.

Number Systems are used in different forms for computational purposes (Decimal),

for managing the database (Octal), to represent the memory locations (Hexa-Decimal)

etc.

No such hardware is there that allows the easy conversion of number systems in one

place (not even Scientific Calculators).

INTRODUCTION

Number System is a mathematical numeration for expressingnumbers in different forms.

Ex :- Binary, Hexadecimal etc.

ALL IN ONE NUMBER SYSTEM is aimed to design a real time

processing system which will be helpful to convert any number

from one system to another number system.

The project will be designed using VlSI Technology on FPGA

(Field Programmable Gate Array).

CURRENT MARKET SOLUTION

No such computing device isthere which comes with the feature

of Number System conversion.

This project will be an extra

feature to these calculators if

implemented practically.


6/21

OUR APPROACH

The design will be implemented using VHDL Language.

VHDL stands for VHSIC Hardware DescriptionLanguage.

The synthesis and simulation prototype will be designed

using the Xilinx ISE and Modelsim Simulator.

The hardware implementation will be done using the

Mission 10x ULK (Unified Learning Kit).

COMPONENTS AND OTHER TOOLS

Mission -10x ULK kit

Synthesis tool : Xilinx Webpack ISE (v-12.1)

Simulation tool : Modelsim Simulator (v-6.5)

4*4 Keypad Matrix

TOOLS DESCRIPTION

1. Mission 10x ULK Kit

16*2 character LCD

FPGA Processor

FPGA

connection

Port

Mode Switch

TOOLS DESCRIPTION (contd.)

1.Mission 10x ULK Kit (contd.)

The Character LCD will be used to show the input given

to the system and the output received.

It will also show the input and output modes of the

Number System.

The FPGA processor will be configured with the HDL

Language to act as ASIC i.e. Application Specific

Integrated Circuit.


10/21


2. Xilinx ISE Webpack

Xilinx ISE is a platform which provides the work

environment for designing the logic of the ASIC.

The logic may be designed using two Hardware

Description Languages, which are as follows :

i.) VHDL

ii.) Verilog

This project will be designed using VHDL.

3. Modelsim Simulator

A simulator is used to check if a designed logic is correct

or not theoretically.

It cant tell whether the logic is hardware compatible or

not.

However, it shows the user, the output according to the

the logic implemented.

4. 4*4 Keypad Matrix

The Keypad Matrix is used for

giving input and selecting mode

of the number system.

This keypad will be designed on

a PCB Board using Push to On/Off

switches and will be interfaced to

the ULK kit.


15/21

WORKING

The program is loaded onto the FPGA processor usingJTAG or ETHERNET cable.

The mode will be selected via mode switch so that

the keypad will work either to input the data or to

choose the mode of conversion.


16/21

WORKING (contd.)

Following are the modes available for the conversion:

1. HEX TO BIN.

2. HEX TO DEC.

3. HEX TO OCT.

4. BIN TO DEC.5. BIN TO OCT.

6. BIN TO HEX.

7. DEC. TO BIN.

8. DEC TO OCT.9. DEC TO HEX.

0. BIN TO GRAY.

A. GRAY TO BIN.

B. BIN TO EXS-3.


17/21

WORKING (contd.)

The input given by the user will be shown on the 1st row

of the character LCD while the output will be shown on

the 2nd row.

APPLICATION & FURTHER ENHANCEMENTS

This project can be used by students for computationalpurposes regarding number system conversions.

Can be used in applications related to microprocessors

where data needs to be essentially in Hexadecimalformat or in UNIX systems where Octal number system is

used to set file permissions.

For future enhancements, various other features like

arithmetic operations may be added to the project.
