抄録

This paper presents an H.264/AVC intra prediction design for Super Hi-Vision (SHV) video. Due to huge throughput requirements, design challenges such as data dependency and complexity become even more critical. To solve these problems, we first propose an interlaced block reordering scheme together with a coarse-to-fine mode decision (CFMD) strategy to resolve the data dependency between intra mode decision and reconstruction. Circuits area is reduced in the meantime with CFMD. We also propose a probability-based reconstruction scheme to solve the problem from long pipeline latency. As a result, hardware complexity in terms of the product of area and frequency is reduced by 74%. The maximum throughput reaches 1991Mpixels/s for 7680×4320p 60fps video. Total logic gate count is 451.5k in 65nm library.
