H.264/AVC intra-frame encoding contains several computation-intensive coding tools that form a long data dependency loop that is difficult to speed up. In this paper, we present a low-power and high-performance H.264/AVC intra-frame encoder. We propose several novel approaches to alleviate the performance bottleneck caused by the long data dependency loop among 4 × 4 luma blocks, integrate an efficient...
In this work we present a novel optimal buffer control approach for H.264/AVC low-delay applications by dynamically allocating computational complexity (such as a number of CPU clocks) and bits for encoding each coding element (basic unit) within a video sequence, according to its predicted MAD (Mean Absolute Difference), while considering buffer size limitations (preventing underflow/overflow of...
