Performance Analysis of Video PHY Controller Using Unidirection and Bi-directional IO Standard via 7 Series FPGA

The Video PHY controller offers an interface between transmitters/receivers and video ports. These video ports are categorized in HDMI or Displayport. HDMI Video PHY controller are mostly used for their high speed operation for high resolution graphics. However, the execution of high resolution graphics consumes more power, this creates a need of designing the low power design for Video PHY controller. In this paper, the performance of Video PHY controller is analyzed by comparing the power consumption of unidirectional and bi-directional IO Standard over 7 series FPGA. It is determined that total on-chip power is reduced for unidirectional IO Standard based Video PHY controller compared to bidirectional IO Standard based Video PHY controller. The most significant achievement of this work is that it is concluded that unidirectional IO Standard based Video PHY controller consume least standby power compared to bidirectional IO Standard based Video PHY controller. It is defined that for 6 GHz operated frequency Video PHY controller, the 32% total on-chip power is reduced using unidirectional IO Standard based Video PHY controller is less compared to bidirectional IO Standard based Video PHY controller. It is also demonstrated that 97% device static power i.e. standby mode power consumption is reduced using unidirectional IO Standard based Video PHY controller is less compared to bidirectional IO Standard based Video PHY controller. The proposed design will be to provide high resolution video processing at low standby power consumption using unidirectional IO Standard based Video PHY controller is less compared to bidirectional IO Standard based Video PHY controller.
