Bit Reversal on Uniprocessors
Bit reversal, hierarchical memory, Fast Fourier Transform Many versions of the Fast Fourier Transform require a reordering of either the input or the output data that corresponds to reversing the order of the bits in the array index. There has been a surprisingly large number of papers on this subject in the recent literature. This paper collects 30 methods for bit reversing an array. Each meth...
متن کاملOptimum Drill Bit Selection by Using Bit Images and Mathematical Investigation
This study is designed to consider the two important yet often neglected factors, which are factory recommendation and bit features, in optimum bit selection. Image processing techniques have been used to consider the bit features. A mathematical equation, which is derived from a neural network model, is used for drill bit selection to obtain the bit’s maximum penetration rate that corresponds ...
متن کاملOptimum bit allocation and decomposition for high quality audio coding
Current audio compression schemes are capable of reducing the per channel bit rate of high quality audio signals from 16 bits per sample to around 2-4 bits per sample. In these schemes, knowledge of psychoacoustics is utilised and a uniform or nonuniform frequency decomposition method is used. In this paper we derive the optimum bit allocation to achieve the highest perceptual quality under a f...
متن کاملOptimum bit rate for image transmission over underwater acoustic channel
In this paper, image transmission in underwater channels is considered. The images are encoded with forward error correction using an unequal error protection technique together with the Reed-Solomon codes and dynamic bit-rate allocation before transmitted. This paper proposes a novel rate allocation scheme for efficient image bit stream transmission in underwater acoustic channels with optimum...
متن کاملEfficient Bit Reversal Algorithms in Parallel Computers
Fast Fourier Transform is widely used in many areas of engineering and mathematics such as digital signal and image processing systems, and polynomial multiplication. Furthermore, it has an important role in performing parallel simulations such as plasma simulation, weather forecasting, and dynamic fluids. Bit-reversal routine is considered to be an essential part of FFT and that is because of ...
