Video processing is foundational to a spectrum of important workloads: video sharing, video conferencing, photos/video archival, virtual/augmented reality, cloud gaming, and live streaming. The exponential growth in these workloads, coincident with a slowing Moore's law, poses significant challenges to deliver more computing at higher efficiencies. In this article, we present the design of a new accelerator-the video coding unit-targeted at warehouse-scale (cloud) video transcoding. Our deployment at scale in Google, the first of its kind, has demonstrated significant benefits on several products (YouTube, Meet, Stadia, Photos, etc.) serving billions of users.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
