This paper presents a report tool, based on a nonlinear model with the cell as its underpinning theory. The design of this report tool is based on analysis of plenty of complex Chinese-style reports, and the cons and pros of current report tools from home and abroad. The report tool can design reports with multiple sections using multiple data sources, irregular grouping, dynamic calculations between...
One Super Hi-Vision (SHV) 4k times 4k @60 fps fractional motion estimation (FME) engine is proposed in our paper. Firstly, two complexity reduction schemes are proposed in the algorithm level. By analyzing the integer motion cost, 48% clock cycle is saved based on our mode pre-filtering scheme. By further check the motion cost of neighboring search points, our directional one-pass scheme can achieve...
In this paper, we contribute one reconfigurable integer motion estimation (IME) architectures (namely RPPSAD) based on adaptive algorithm. Firstly, based on the pixel difference analysis, the spatial redundancy is further exploited and three subsampling patterns are selected adaptively for the IME process. Secondly, in order to achieve data reuse and power reduction in memory part, the reference pixels...
In this paper, we contribute a configurable SAD tree architecture based on adaptive subsampling scheme. Firstly, by further exploiting the spatial feature, the integer motion estimation process is greatly sped up. Secondly, the conventional partial sum of absolute difference (SAD) based pipeline structure is optimized into configurable SAD oriented way, which enhances the performance and solve the...
The latest video coding standard H.264/AVC can provide excellent performance compared with previous standards. However, the introduction of new techniques in motion estimation also brings about heavy burden of computation complexity on the video coding system. In hardware field, the subsampling technique is widely used to reduce hardware cost and release computation burden of ME engine. However, direct...
