Discrete Hartley transform (DHT) is an important tool in digital signal processing. In this paper, based on our previous work of performing DHT via linear sums of discrete moments, we have made development to eliminate multiplications in discrete Hartley transforms by performing appropriate bit operations and shift in binary system, which can be implemented by integer additions of fixed points. An...
Window operations which are computationally intensive and data intensive are frequently used in image compression, pattern recognition and digital signal processing. Reconfigurable hardware boards provide a convenient and flexible solution to speed up these algorithms. This paper studies the effect of loop unrolling on the area, clock speed and throughput based on a data schedule method to find the...
Fourth-order cross moments are used in modern digital signal processing as a powerful analytical tool for the synthesis and analysis of signals and systems. Computing fourth-order cross moments from incoming time-series data is computationally intensive process and requires fast computing systems and parallel processing techniques to meet the real time processing requirement. An algorithm based on...
