• Tech Lead of Low Power Module in Nvidia Graphics driver.
• I am responsible for defining roadmap/vision for LowPower module. These are my high level responsibilities for each LowPower project -
• Finalise the requirements for project
• Propose high level HW and SW design to meet the requirements
• Estimating resource requirements based on timelines
• Detailed design
• Project execution and delivery
• Development and verification based on BW availability
• These are projects delivered by me. I was Tech lead for these projects-
• 1) Power Module: Pascal Architecture (2 Years)
• Introduced new Architecture for LowPower module. Unified architecture in HW, Firmware and SW that reduced complexity of overall module and made it quite robust.
• Meet the CEC winidle requirements
• Optimise Battery power by synchronising activities of different components (NAD)
• Make Power Module compatible with new HW features coming in Pascal (e.g Some security enhancements, Wireless display etc).
• Unified Tool to collect GPU power data and debug GPU power sates
• 2) Power improvements: Nvidia’s Notebook GPU production cycle – 2014 (6 months)
• Regulator efficieny improvements for batched workloads (e.g Frame rate limiter)
• 3) Power Module: Maxwell Architecture - GTX970 and GTX980 (6 months)
• Improve the Frame Buffer power consumption for light work load use case.
• GeForce GTX980 Low Power Module Bringup and Production.
• 4) Power improvements: Nvidia’s Notebook GPU production cycle – 2013 (6 Months)
• Production of existing POR features
• In addition to these projects, I worked on improving testing infrastructure for Lower Power module:
• Cover all corner case in pre-silicon and post silicon verification
• To optimise total resource (Dev and QA) BW required for verification
• Reduce the automation effort

• Software Developer for different power saving features in Low Power Module of Nvidia Graphics Driver.
• Key Deliverables:
• Optimized space and time complexity of power saving features. Internal Microcontroller manages these features.
• Enhanced power saving feature to put DRAM (Frame Buffer) into power saving mode. Did the Bring-up of same feature on GeForce GTX750 GPU.
• Designed and implemented power saving feature to save power by improving voltage regulator's efficiency.
• Enhanced Software Power Regression System (SPRS). SPRS evaluates GPU power consumption under low, medium and high performance workloads on each nightly driver build. I designed APMS Tool (Automated Power Measurement System) to effectively automate jobs in SPRS.
• GeForce GTX680 GPU Bring-up.
