We introduce Dynamic Dual Fixed Point (DDFX) CORDIC, that relies on run-time alteration of the numerical format of the Dual Fixed Point (DFX) CORDIC hardware. This allows for enhanced dynamic range and accuracy. Fixed Point, Dual Fixed Point, Floating Point, and Dynamic Dual Fixed Point CORDIC units are compared in terms of resources and accuracy. Results show that the hardware/software approach achieves...
We introduce Dual Fixed Point CORDIC, that provides a compromise between Fixed Point and Floating Point CORDIC hardware implementations. A fully parameterized hardware is presented that allows for extensive exploration of the resources-accuracy design space, from which we generate optimal (in the multi-objective sense) realizations. We compare Fixed Point, Dual Fixed Point, and Floating Point CORDIC...
Digital systems capable of altering their hardware configuration on the fly are labeled dynamically reconfigurable. Proteus is an OpenRISC-based computer optimized for Xilinx's FPGAs that can dynamically reconfigure itself. Proteus was conceived as a platform to facilitate the study of reconfigurable computing architectures by providing a turn-key solution that is openly available. This paper describes...
In this paper, we report the adsorption of phenol and nitrophenols (2,4 dinitrophenol, 4-nitrophenol and 2-nitrophenol) on a novel carbon material: carbon nanospheres (CNS). CNS were prepared by the direct pyrolysis of benzene and characterized by N 2 adsorption–desorption, X-ray diffraction analyses (XRD), scanning and transmission electron microscopy (SEM and TEM) and Raman spectroscopy...
