WORK EXPERIENCE

Graduate Teaching Assistant: Worked as a Graduate Teaching Assistant at

University of Texas-Arlington for Advanced Microprocessors Class and

Embedded Microcontrollers from Sep 2009 - Dec 2009

Duties involve:

. Teaching students, grading their tests.

. Helping them with their class projects, debugging the project circuits

and managing the project lab.

Pre-emptive Real Time Operating System (UTA Fall 2009): Developed a pre-

emptive RTOS for PIC 24f series of 16 bit micro controllers. The project

involved developing an RTOS from scratch. Context saving as well as

switching was taken care of as well as various other aspects like use of

semaphores for resource handling, system timers and scheduler for the

system was built in the project.

PROJECTS

Wireless Mesh Control with Ethernet Bridge Controller:

* Built hardware and software for the microcontroller and its interfaces.

Designed a protocol for communication between the wireless system.

The wireless network bridged to an 802.3 Ethernet 10BASE-T network with an

HTTP interface.

Wrote device drivers for the system.

Cooperative Real Time Operating System:

* Wrote a code in C which implements a cooperative RTOS

* Used semaphores, system timers, priority schedulers etc. for

implementing the RTOS. (Advanced Embedded Microcontrollers).

Timing Intensive Asynchronous Communications Interface:

* Built the hardware and the software (assembly language) for implementing

a DMX512-A protocol (Embedded Microcontrollers).

5 Stage Pipelined Processor Design:

* Work included design of a 32 bit processor with Harvard Architecture

running on a RISC instruction set.

* Stalling as well as data forwarding for different stages was also

designed.(Advanced Microprocessors)

Cache control emulation:

* A C code emulation of set associative as well as direct cache

architectures to determine the maximum number of cache hits in either

case and hence determining a better architecture for the given case.

* Used MRU algorithm.

* AMAT Calculations were used to determine the basis of best architecture.

WAV Audio Player:

* Built an interrupts driven WAV audio payer on DSK5509a.

* Input was provided form SD card, the on-chip DMA was used for data

transfers between processor and SD card.

. The project involved implementation of SD protocol and FAT16 file system

the data processing was done using AIC23 protocol. (Individual Project)

pH Measurement System with Automatic Temperature Compensation:

* Built a system that measures the pH of a given solution and the results

are adjusted pertaining to the

temperature dependencies of pH.

* Includes signal conditioning for the system, data acquisition from

temperature as well as pH sensor, and other

system design parameters. (Instrumentation and Measurement)

Message Relay Server:

. Designed a simple message relay client/server model using Java.

. Implemented the concept of sockets for data transfer between two client

processes which are connected to a common server process. (Computer

Networks).

IP Router Emulation:

* Implemented basic functions of an IP router, and applied systems

programming constructs similar to those

found in the IP implementation in a typical Linux router. (Computer

Networks)

Heart Rate Monitoring System:

* Built a system that could measure the heart rate of a person using a

photo resistor and the analog data acquired

was processed by an 8051 micro controller giving a pulse reading.
