Project 1:

Title : Design and Development of Integrated Seeker

Electronics.

Description : The signal from the Intermediate frequency unit is fed to

16 bit high speed ADC. All the signal processing job is

done in the FPGA (virtex5 SX95T). Finally this processed

data is send to other FPGA (Virtex5 FX130T) which has two

hard core power pc in which one is used for controlling all

the sub systems and used for 1553B communication and other

processor is used for Doppler tracking, range tracking and

processing of algorithms. The processed data is sent to the

master processor for further using FSL link or Shared BRAM.

My contributions:

. Implemented Multiprocessor, Multithreading concepts in FPGA.

. Implemented XilKernel (POSIX Compliant) to have Real-Time control on

process using ROUND ROBBIN AND PRORITY SCHEDULING CONCEPTS.

. Implemented a DUAL PROCESSOR CORE for communicating various peripherals.

. Implemented Interprocessor communication using FSL and Mailbox methods.

. Implemented data transfer using DPRAM between two processors (soft-core

and hardcore).

. Implementation of range tracking, Doppler tracking algorithms and

firmware of peripherals.

. Chip scope is used as analyzer for the processor and logic.

. Interfacing various peripherals using different Busses (AXI, PLB4.6,

PLB3.4 and OPB bus).

. Implemented Dynamic Allocation for Scratch-Pad Memory at run time.

. Implemented logic and use of IPCORE provided by Xilinx.

. Stimulation of DSP concepts using Matlab.

Tools Used : Xilinx EDK (Embedded Development Kit), Xilinx SDK (Software

Development Kit), uCOS-II and XilKernel, chip scope, Matlab and Orcad.

Project 2:

Title : Software Defined Radio (SDR) for Data Communication.

Description : The signal from the LNA(Low Noise Amplifier) is fed to a

band pass filter then followed by a 14 bit high speed ADC.

the digital data is passed through a digital band pass

filter then multiplied with NCO (numerically controlled

oscillator) to get I and Q channel data. This I and Q

channel data is decimated and passed to a low pass filter,

To bring the signal into baseband, then finding the FFT to

know the frequency of the signal. Then finding the phase

and latter passed to the pre amplifier.

My contributions:

. Implementation of digital filters, NCO (Numerically Controlled

Oscillator).

. Implementation of DSP algorithms.

. Stimulation of DSP algorithms using Matlab and Simulink for finding the

Coefficients of the filters.

. Implementation of firmware development of peripherals.

. Implemented logic and use of IPCORE provided by Xilinx.

. Stimulation of DSP concepts using Matlab.

. Design and stimulation of analog circuit using PSPICE.

. Designing of preamplifier and amplifier.

. Designing of schematics using Cadence Allegro.

. PCB routing using Cadence Allegro and Signal Integrity using Hyperlinks

software.

Tools Used : Xilinx ISE, chip scope, Matlab, simulinks, pspice and Orcad.

Project 3:

Title: Design of RADAR Control Computer and Simulator for

Controlling the RADAR Computer.

Description : The aim of the project is to design a RADAR control

computer and Real Time software, which runs on the control

computer using 32-bit Xilinx Micro Blaze Soft-Core

Processor. This computer communicates with different sub

systems and does the required data processing and furnishes

data to sub systems upon requests. This acts as a

supervisor among all the sub-systems. The debugging of

RADAR controller can be done with simulator by having a RS-

232 communication. Simulator and GUI can be used as in-

house testing of the controller with other sub systems.

My contributions:

. Developed C-Language programs in Xilinx SDK, to interface sub-systems

with radar control computer.

processor (Developed firm ware for these peripherals) and their

performance testing.

. Developed and executed a Test Suit to test the Unit by interfacing the

test suit to the GUI developed in VB.

. Developed a GUI application in VB to interact with the radar control

computer from PC through RS-232 communication to avail automation in

testing and to demonstrate the operation of radar control computer.

. Development of hardware for simulator.

. Designing of schematics of simulator using Orcad.

Description: Aim of this project is to intimate the failure of

street lights, any short circuitand simultaneously provide

auto on and off. This system has XBEE (RF MODULE) which is

connected to PIC18f452 microcontroller. Data from the

microcontroller to XBEE is send using RS232 communication.

controller displays the status pole on the LCD and Data

Base, The voltage across the Shunt resistor is read by the

ADC port of the PIC18f452 controller to find any presence

of short circuit. This data is stored in a Data Base at

regular intervals of time which is sent using slave XBEE to

the master XBEE. Change in intensity of light is found
