EXPERIENCE:

Embedded Firmware Engineer (Viaan Electronics) (April 2017-Present)

-Developing low levels devices drivers or application code for embedded devices in C.

-Developing Software solutions by studying customer needs.

-Demonstrating Solutions by Documentations, Flowcharts and Clear Code.

ACADEMIC PROJECTS:

Implementing self driven and self guided Unmanned Vehicle using RTOS & Cortex M4F series ARM controller

(December2016-February 2017)

- Implementing RTOS to develop various threads for sensing the magnets on the road through DRV50353 Analog Bipolar Hall effect sensor and using that readings to control the speed of the motors by using PWM and DRV 8833 Dual H Bridge Motor Driver. Self guiding the vehicle using this sensor data and controlling the motor speeds.

- Controlling the vehicle start and break through cell phone using Bluetooth 4.0 BLE module mounted on the vehicle and also monitoring the vehicle data and displaying it on the cell phone using this module.

Emulating the cache controller to determine the best cache memory architecture.

( University of Texas at Arlington, October 2016-December 2016)

- Determined the best architecture for 256 KB of Cache including associativity (N), cache lines (L), block size(B).

- Incorporated write strategies like Write Back, WriteThrough Allocate, Write Through Non Allocate and Replacement strategies like LRU and Round Robin to access SDRAM.

- Analysed a total of 96 Combinations of N(1,2,4,8), BL(1,2,4,8), 3 Write strategies and 2 replacement strategies by calculating the Average Memory Access Time assuming the Miss Penalty is 90ns, first memory access time is 15ns and subsequent memory access time is 1 ns.

Designing a 32-bit RISC microprocessor with the 4-stage pipeline.

( University of Texas at Arlington, September 2016 –October 2016)

- Designed the control logic for instruction memory and data memory interfaces, register map interface, ALU and a full resolution of all structural, control and data hazards for proper pipeline operation.

- Also controlled the flow of the instructions through the pipeline including interrupt handling.

Internet of Things (IOT).

( University of Texas at Arlington, April 2016 – May 2016)

- Designed an Internet of Things node that has intelligence to send an SMS to the user via internet depending on the triggers received and the rules set for a particular event.

- The node was designed using ARM cortex M4F and connected to the internet via ENC28j60 Ethernet module. It implemented TCP to connect to a third party website and submit the form. Also implemented DNS service to get the ip address of the website. The node also supported others protocols like ICMP for ping, ARP and UDP for internal communication with the central connecting unit

Designed a Preemptive and Cooperative RTOS from scratch using Cortex M4F series ARM controller.

( University of Texas at Arlington, January 2016 – March 2016)

- Designed RTOS on Tiva C series cortex M4F ARM using kernel functions like yield, sleep in coordination with systicktimer, wait, post,with the semaphores

- Programmed a prioritized kernel scheduler that schedules processes based on their state and priority.

- Designed cooperative RTOS using non SVC call method and premptive using SVC call method.

Embedded Micro-controller project on 32-bit ARM® M4F core @ 80MHz - TM4C123GH6M Controller.

( University of Texas at Arlington, September 2015 – December 2015)

- The goal of this project is to build a device capable of acting as either a controller or device for a timing intensive asynchronous communications interface based on the DMX512-A protocol with EF1 topology.

- The PC transmitter will accept commands from a PC via an RS-232 interface and will continuously transmit a serial stream to control up to 512 devices on a RS-485 communication bus.

- The PC receiver will forward data received from devices on a communications bus and send these to the PC with the RS- 232 interface.

Designing of SDRAM controller to interface MT48LC4M16A2 SDRAM memory with 80386SX processor:

( University of Texas at Arlington, January 2015 – May 2015)

- Designed an SDRAM controller that allowed SDRAM memory MT48LC4M16A2 to be interfaced with an 80386SX microprocessor having only asynchronous memory support.

- A complete controller solution including state machine, row, column, and bank signal generation, data masking, data flow, ready logic, and refresh support was designed.

Forest fire prevention and field management:

(University of Mumbai, June 2012 – May 2013)

Implemented a circuit that could control and prevent forest fires by detecting them and installing sprinklers in forest areas. Another part of the project was farming control which could control ploughing, seeding and irrigation mechanism from a remote station.
