  • Video decoder firmware on Qualcomm’s Venus video core
  • Lead the effort to design and implement the VC-1 decoder in a multithreaded manner on this platform.
  • Worked on thread task allocation, interrupt management and synchronizing the various threads.
  • Also worked on pushing common functionalities into a set of common functions shared by all decoders.
  • Initial VC-1 bring-up on the next generation Venus 3.0 HW and also took the lead in implementing MPEG4/H.263/MPEG2 decoders on it.
  • Also implemented features required by the application layer such as flush, pause/resume, thumbnail mode, error resilience etc.
  • Contributed to the software-firmware interface design and it’s firmware side implementation
  • Mentored new team members on our overall system and decoder firmware srchitecture
  • Worked with the application layer team to integrate the firmware and iron out teething issues.
  • Testing on the Veloce Emulation System and the reference board
  • Found some crucial HW bugs before tapeout that would have impacted decoder performance.
  • As a workaround for a HW issue found after tapeout, I implemented the entire VC-1 bitplane decode block in firmware and optimized it for ARM9 to ensure no performance penalties.
  • RTOS Kernel modification
  • Studied the RTOS architecture and made the necessary kernel level modifications to add support for multiple threads at the same priority.
