Synopsis of Projects:
Project#1
Project Name : Virtual SCSI HBA
Role : Software developer.
Team : 4
Description :

2. This simplest form of this project is to make a file in the file system appear as a
disk. This kernel driver allows the user programs to create, delete and service SCSI low
level HBA (LLD). The user program can create, register and service SCSI HBA.
Project#2
Project Name : SCSI Commands
Role : Software developer.
Description :
Implemented below listed SCSI commands and integrated to GUI based SCSI tool
implemented in Crimson.
SCSI commands list: INQUIRY, RELEASE_10, RESERVE_10, START, STOP, SYNC_10,
SYNC_16, TUR commands.
Project#3
Project Name : FUN LEARN
Role : Software developer.
Description :
Designed hardware circuit for 4/4 keypad and interfaced with LPC 2148. Then
developed handlers for each keypad button where it works on interrupt mode. Later
these routines were integrated into applications to provide appropriate functionally for
each keypad press. Also for debugging purpose, implemented routines to format the
strings and send over serial port.
Project #4
Title : Design of optimal Degaussing Electronics for Ring Laser
Gyroscope
Description : Designing the degaussing Electronics to remove the unwanted magnetic
field efficiently in Ring Laser Gyroscope by using PWM timer of AT90S2313
microcontroller.
Project #5
Title : Employee Authentication for Door Access Control.
Team : 4
Role : Design of LCD and microcontroller circuit,
Software developer.
Description :
This project takes Employee ID, Password through Keypad with reference of LCD.
Then, it verifies these details with stored information from EEPROM, if matches Door
opens otherwise remains closed with help of Relay circuit.
Project#6

3. Title : Designed GUI for performing all operations of
Micro-controller
Role : Software developer.
Description :
This project will automate the job of all micro controller operations using Python
GUI tool, whenever user wants to do some specific operations of micro controller can be
done using GUI tool for implementing this task there will be one DB-9 serial port
between PC and embedded board for communicating. Operations of various interfaces to
micro controller can be done by porting specific hex file on to board.
Project #7
Project Name : Interacting with PCI device.
Role : Software developer
Description :
This is a kernel object (.KO file act as a module) if we insert this module it will
interact with the attached PCI device. The desired specifications of PCI device will be
stored in kernel buffers.
Project#8
Title : Cache allocation module on Linux kernel.
Role : Kernel programmer.
Description :
This module for Linux kernel module for creating slabs, objects in allocated cache
with user required size. It facilitates to use the space for user read, write in which read
cannot happened when cache is empty, write cannot happened when cache is full.
Project#9
Title : Adaptive Bilateral Filtering for Sharpness
Enhancement and Noise removal.
Description :
I have implemented an adaptive filtering technique to remove noise at edges as
well as sharpening the image by using MATLAB tool.
