Popis: A lower power and area efficient VP9 and multi-standard video decoder chip is first-reported for Android 4K TV. It supports prevalent MPEG-x, VP-x, RMx, WMV-x and H.26x series video standards in a single chip. Three high-throughput techniques, look-ahead re-mapping, early stage pipeline and dynamic-scheduled bus translation, are proposed. They cuts the processing times by 51.2% compared to the state-of-the-art design [4]. Moreover, two area-efficient techniques, hybrid backward probability update and tile-to-raster scan ordering, are designed to reduce the internal memory size by 10%. A mass-production chip is fabricated in a 28nm CMOS technology with an energy efficiency of 0.19nJ/pixel and an area of 2.6mm2. Compared to the dual-core decoder design [4], this work achieves the identical performance (4K@60fps) with single core which cut one-half of chip area.
