BurstLink: Techniques for Energy-Efficient Video Display for Conventional and Virtual Reality Systems
Year: 2021
Type: conference-paper
Abstract: Conventional planar video streaming is the most popular application in mobile systems. The rapid growth of 360° video content and virtual reality (VR) devices is accelerating the adoption of VR video streaming. Unfortunately, video streaming consumes significant system energy due to high power consumption of major system components (e.g., DRAM, display interfaces, and display panel) involved in the video streaming process. For example, in conventional planar video streaming, the video decoder (in the processor) decodes video frames and stores them in the DRAM main memory before the display controller (in the processor) transfers decoded frames from DRAM to the display panel. This system architecture causes large amount of data movement to/from DRAM as well as high DRAM bandwidth usage. As a result, DRAM by itself consumes more than 30% of the video streaming energy.
