Dedicated hardware accelerators enable energy-efficient implementations of radio and imaging basebands. Multistandard, multi-mode radio basebands require an on-the-fly reconfigurable fast Fourier transform (FFT) accelerator that implements many different FFT sizes. An instance of a runtime-reconfigurable 2n3m5k FFT accelerator was generated by a custom hardware generator to meet the requirements of...
A Factor Graph (FG-http://en.wikipedia.org/wiki/Factor_graph) is a structure used to And solutions to problems that can be represented as a Probabilistic Graphical Model (PGM). They consist of interconnected variable nodes and factor nodes, which iteratively compute and pass messages to each other. FG's can be applied to solve decoding of forward error correcting codes, Markov chains and Markov Random...
W artykule przedstawiono analizę podstawowych metod generowania liczb losowych, wskazując na zalety sprzętowej realizacji takich generatorów. Wykorzystując generatory zbudowane na dwóch LFSR-ach opracowano i zbudowano szesnastokanałowy generator liczb pseudolosowych w strukturze FPGA. Zaproponowano wykorzystanie takiego generatora do budowy sprzętowych generatorów liczb losowych o rozkładach wykładniczym...
