Confidential,Bangalore 07/2009 to 11/2009
Project Lead

The scope of the project is to implement a Software Watchdog Timer (SWT) using C++ in Linux. The software watchdog waits until a specific event occurs and executes a preconfigured action. The software watchdog uses a built-in counter to count down to zero from a defined timeout value. When the watchdog reaches zero, it executes the predefined expiration action. To prevent the watchdog from timing out, the application can reset the watchdog count. If your application stops running, the watchdog counts down to zero and then carry out the expiration action. The major advantage of this SWT over the already existing Software watchdog daemon in Linux would be that this SWT is designed to kill and restart only the process that is faulty and not the entire system as done by the Linux Software Watchdog daemon.
Responsibilities:

• Involved in Understanding the scope of the project along with Analysis and design(through HLD preparation) ,
• Is Responsible for Analyzing the design constraints and coming up with the suitable approach to resolve the issue.

Software Engineer

Project 1. Data loading Subsystem through Ethernet

VDR is embedded equipment mainly dedicated to in flight data storage and uploading of data to other equipments. The VDR is connected to OAC master through Ethernet connection. TCP/IP protocol is used. The Video Digital Cartridge is used for uploading the data to the aircraft for providing the pilot with flight plan, waypoint airfield and magvar databases. Along with this the downloading of data to the equipments is also done through this subsystem. The uploading of the data from cartridge to OAC-Master is done through Ethernet using socket for inter-process communication and Downloading to equipments is done through 1553 bus in the form of messages.

Responsibilities:

• Responsible for development and Integration testing of the module
• Involved in the simulation of the project using the Vx-Works simulator.
• Involved in the Integration testing of the module with the Master module.
• Performed the Black box testing using the RTRT.

Environment: C++, Ada95,vxworks,TCP/IP,RTRT,Socket program

Project 2. Simulation Project for Display surfaces of LCA

The project simulates the Cockpit Display Surfaces of the LCA (Light Combat Aircraft. The simulation has two applications running on two different cards. The OACMASTER running on one card composes the data and puts to the shared memory. The display simulation running on the other card copies the data from the shared memory and draws the display surfaces using the Graphical language OpenGL. The inter Process communication is achieved using semaphores for synchronization between two processes. The cockpit environment has a number of display surfaces which display different pages to the pilot during navigation and during maintenance. To check the functionality of OACMASTER, which is central processing part of LCA these simulator surfaces are developed.

Responsibilities:

• Responsible for Analyzing the Use case and develop the simulation model to check the functionality of the different pages displayed in the cockpit to the Pilot.
• The Graphical Display was developed using the open-GL to meet the requirement as per the specification.
• Involved in the development and certification of the simulation model.
• The semaphore concept is used for the Inter-process communication between the OACMASTER and Display surfaces as these will be running on different cards. The data is transferred or received through the shared memory.
• Messages are produced and sent for testing purpose to validate the pages displayed.

Environment: C++, Ada95, RTRT, OPEN-GL, Inter-Process Communication, Shared Menory.
