A display driver, also known as a graphics driver or video driver, is software that enables communication between the operating system and the graphics hardware (such as a graphics card and integrated graphics processor) in a computer system. Its primary function is to facilitate the rendering and display of graphical information on the monitor or screen.Responsibilities:· Understanding the code flow, verify with module or component.· Environment setup in Vector Cast with respective module.· Writing test cases and maintain note section with requirement based.· Generate full report and test case Management report.· Generate test results and test reports by executing on Target compiler (MinGW)· Identify defects and raise the issue if exist.· Refactored existing code to remove unwanted functions as per requirement.· Fix the code to eliminate warnings as per MISRA rules.

Operated in Band - IV(4400 MHz to 5000 MHz) capable of Full – Duplex Data transferring up to 100 Mbps.· Worked for Indoor Data Processing Unit (IDU)· Worked on SNMP for set and get requests through Network Management system to IDU and ODU and SNMP trap implementation for indicators.· Worked System calls used for message queues, all processes could exchange information through access to a common system message queue on IDU side,each message is given an identification or type so that processes can select the appropriate message from both sides IDU and ODU.· Process must share a common key in order to get access to the queue in the first place.· Worked for VOIP application to establish calls between systems point to point communication and Multi point communication and to improve overall performance of the VOIP application by optimizing the sound device latency and the jitter buffer and also worked for secure calling. Used PJsip for this application.· Complete Coding of programming GPIO and reading the data.· Linux host system is used as the cross compiling station,before start compiling libraries to be installed on both devices (x86 machine, ARM machine)Created Make file for this application and built for Arm platform
