FlexCore: Massively Parallel and Flexible Processing for Large MIMO Access Points

TL;DR: FlexCore is presented, the first computational architecture capable of parallelizing the detection of large numbers of mutually-interfering information streams at a granularity below individual OFDM subcarriers, in a nearly-embarrassingly parallel manner while utilizing any number of available processing elements.
Journal ArticleDOI

Reduced Complexity Superresolution for Low-Bitrate Video Compression

TL;DR: This paper combines state-of-the-art coding and superresolution (SR) techniques to improve video compression both in terms of coding efficiency and complexity and proposes a novel SR algorithm to advance the critical bitrate at the level of 10 Mb/s.
Journal ArticleDOI

Acceleration techniques and evaluation on multi-core CPU, GPU and FPGA for image processing and super-resolution

TL;DR: The current paper builds up on the characteristics of the L-SEABI SR method to introduce parallelization techniques for GPUs and FPGAs for super-resolution reconstruction and confirms the benefits of the proposed acceleration techniques by employing them on a different category of image processing algorithms.

Massively Parallel Tree Search for High-Dimensional Sphere Decoders

TL;DR: This work presents the design and VLSI architecture of MultiSphere; the first method to massively parallelize the tree search of large sphere decoders in a nearly-concurrent manner, without compromising their maximum-likelihood performance, and by keeping the overall processing complexity comparable to that of highly-optimized sequential sphere decmoders.
