A single-chip HEVC (H.265) 8192×4320p encoder is implemented on a 25mm2 die with 28nm process. It dissipates 708mW at 312MHz for 8192×4320p encoding. Frame-level pipelining reduces 8.90 GB/s external memory bandwidth and improve CABAC rate by 50%. A 7.14MB three-level memory hierarchy is designed to support internal 43.38 GB/s bandwidth and 13-port accesses, and reduces external reference frame bandwidth...
3DTV promises to become the mainstream of next-generation TV systems. High resolution 3DTV provides users with a vivid watching experience. Moreover, free-viewpoint view synthesis (FVVS) extends the common two-view stereo 3D vision into virtual reality by generating unlimited views from any desired view point. In the next-generation 3DTV systems, the set-top box (STB) SoC requires both a high-definition...
The IEEE 802.16 standard is considered to be one of the most promising technologies. Bandwidth reservation is employed to provide quality of service (QoS)-guaranteeing services. A request/grant scheme is defined in the IEEE 802.16 standard. There are two types of bandwidth request (BR) mechanisms, i.e., unicast polling and contention resolution, which are defined in the standard. As specified, connections...
