Alphamosaic Ltd was a UK semiconductor company specializing in low power mobile multimedia processors, based on their VideoCore architecture. Alphamosaic was spun out of its parent company, Cambridge Consultants, by Robert Swann and Steve Barlow in 2000. The technology centered round a novel 2D digital signal processor (DSP) architecture for low-power processing of video and images. It was used in consumer devices including phones from Samsung and the first Apple video iPod. In September 2004, Alphamosaic was acquired by Broadcom for $123m, forming its Mobile Multimedia group on the Cambridge Science Park site.
