Abstract :
A first-reported 4K×2K@60fps digital TV SoC processor supporting 9 video formats and integrating HDMI/MHL receiver is fabricated in a 40nm CMOS process. It adopts error compensation processor (ECP) to improve the visual quality, and designs a memory management unit and resource sharing technique to improve the throughput and area efficiency by 38.5% and 34.3%, respectively. Moreover, a lossless compression processor (LCP) is newly designed to reduce 30% and 45% of external data accesses in playback and gaming scenario, respectively. The proposed TV SoC processor includes multi-standard 4K×2K@60fps playback and 3.4Gbps HDMI receiver (Rx), and both scenario dissipate 198.15mW at 1.2V core and 3.3V I/O.
