(2021)This paper studies the Delta encoding scheme and its effect on power dissipation, for wireless transmission from implantable devices. The study was performed on data from electroencephalographic signals. For the implementation ... -
A Multirate Fully Parallel LDPC Encoder for the IEEE 802.11n/ac/ax QC-LDPC Codes Based on Reduced Complexity XOR Trees
(2021)This article proposes an encoding method based on a two-step encoding algorithm for the 12 quasi-cyclic (QC)-low-density parity-check (LDPC) (QC-LDPC) codes specified in the IEEE 802.11n/ac/ax standards. The proposed ... -
On improving the speedup of slice and tile level parallelism in HEVC Using AVX2
(2017)HEVC has emerged as the new video coding standard promising improved compression ratios (for the same quality) by up to 50% compared to H.264/AVC. To achieve this performance HEVC requires increased computational overhead ... -
On predicting bottlenecks in wavefront parallel video coding using deep neural networks
(2019)Video coding incurs high computational complexity particularly at the encoder side. For this reason, parallelism is used at the various encoding steps. One of the popular coarse grained parallelization tools offered by ... -
Performance evaluation of batch encodings in HEVC using slice level parallelism
(2016)HEVC has emerged as the new video standard to replace H.264/AVC. Although the new standard is able to achieve significantly higher compression ratios compared to the older one, it entails high computational demands. To ... -
Positional data organization and compression in web inverted indexes
(2012)To sustain the tremendous workloads they suffer on a daily basis, Web search engines employ highly compressed data structures known as inverted indexes. Previous works demonstrated that organizing the inverted lists of the ... -
