Description: COCOA is an Application Processor SOC for mp3 players, which includes
ARM922T core and Analog Front End (AFE) chip.
The Power Saving Application helps the
audio device to run for a longer duration with the battery by saving power wherever
possible. One classical example is that it switches off the backlight after a certain
configurable duration. Also based on the format of the song (ex:mp3) this application
fine tunes the clock to run it in the lowest possible frequency to save the power.
Role:
• Designed and developed the modules that switch off the backlight , put lcd, fm
and SDRAM in standby mode, clockgate the unused modules.
PROJECT: Task Switch Visualization for COCOA platform
Description: COCOA is an Application Processor SOC for mp3 players, which includes
ARM922T core and Analog Front End (AFE) chip.
The Task Switch Visualization is designed

indicating the developer about the task switch through the GPIO lines. The output from
the GPIO pins can be given to an oscilloscope for the detail analysis to understand how
each task behaves in the real time scenario.
The RTOS involved in this project is
Segger RTOS. This project requires deep understanding of RTOS.
Role:
• Designed and developed the Task Switch Visualization tool.

Dgipro Systems Pvt Ltd (May 2001 - Oct 2003)
PROJECT: Fast Fourier Transform (1024 point)
Description: FFT converts the signal from time domain to frequency domain. The advantage
of using FFT over DFT is the minimal overhead, thus reducing the multipliers and adders
considerably. FFT core computes the complex forward FFT of a 1024 point. The input data
is a vector of 1024 complex values represented as 16-bit numbers in two’s complement
form. The real and imaginary data are represented as separate 16-bit numbers. The output
is also a 1024 element complex vector represented using 16 real bits and 16 imaginary
bits.
Role :
• Designed and developed 1024 point FFT Algorithm in C
PROJECT: Digital Video Broadcasting (DVB)
Description: DVB is a market-led consortium to public and private sector organizations
in the television industry. Its aim is to establish the frame work for the introduction
of MPEG-2 based digital television services. RS coding is a type of FEC that is being
widely used because of its relatively large error correction capability when weighed
against its minimal added overhead. It is widely used in satellite communication, DVB,
etc.
Role :
• Designed and developed RS decoding algorithm in C
PROJECT: Viterbi Decoder (for K=7 and K=5)
Description: Viterbi decoding is a FEC technique that is particularly suited to a
channel in which the transmitted signal is corrupted mainly by Additive White Guassian
Noise (AWGN). Viterbi decoding has the advantage that it has a fixed decoding time. It
is widely applied in wireless telecommunications, HDTVs, GSMs, etc.
Role :
• Designed and developed Viterbi decoding algorithm in C
PROJECT: Access Procedures and Low Power Modes in Bluetooth

performing the main task in serial communications with computers. The device changes
incoming parallel information to serial data, which can be sent, on a communication
line. A second UART can be used to receive the information. The UART performs all the
tasks, timing, parity checking, etc. needed for the communication.
Role :
• Developed UART driver program in C
PROJECT: Packetizer for Bluetooth baseband protocol
Description: Bluetooth is a new standard Application for Short range Wireless
Communication. The Bluetooth standard is promoted by IEEE & SIG. Bluetooth has been
