The HEVC standard adopts varies of Prediction Unit (PU) modes to perform motion estimation (ME). And the mode with the least rate distortion (RD) cost is chosen as the best mode after transversally comparing all candidate modes, which can achieve the highest coding efficiency but require a high computation complexity. In this paper, a fast PU decision algorithm is proposed. Firstly, the correlation...
A highly-parallel LDPC decoder architecture for 10Gbase-T applications is designed in this paper. Firstly, we reduce the routing complexity and corresponding power consumption by the proposed decoder architecture based on single routing networks. Secondly, the proposed architecture is designed with pipelined layered scheduling and multi-block parallel decoding, which improves operation speed and removes...
A 2304-bit flexible decoder for low-density parity-check (LDPC) codes is presented for Wireless-MAN applications. Based on modified turbo-decoding message-passing (M-TDMP) algorithm, the decoder achieves low complexity as well as fast convergence which produces high throughput of 138 Mbps working at 50 MHz. By adopting a novel scheme for early termination of iteration, the proposed decoder obtains...
Classification of remote sensing textures using Gabor ring filter and ordered spectral histogram is investigated. The proposed approach is based on three steps. First, multi-scale Gabor ring filters are designed for feature extraction. Second, marginal distributions, or called histograms, derived from filtered images by Gabor ring filter, would be sorted by their characterized values. Then we could...
