Methods for scalable levels of parallelism in radix-2 ffts for fpga synthesis
(2014)
The Fast Fourier Transform (FFT) is the main block in many communication systems and signal processing applications, as it allows the fast computation of the discrete Fouier transform (DFT). The DFT, in turn, is used to ...
Design methodology for resource efficient implementation of fast fourier transform cores on field programmable gate arrays
(2012)
This thesis presents an efficient methodology for the hardware implementation of the Pease Fast Fourier Transform (FFT) radix-2 algorithm, in which, structural regularity from the Kronecker formulation is exploited to ...
Program vectorization for reducing energy consumption in embedded systems
(2014)
When it comes to software optimization, speedup is the rst goal that comes to mind. However, as the integration level of electronic circuits continues its exponential growth, power reduction has also become an important ...
Design and analysis of scalable floating point fast fourier transforms on field programmable gate arrays
(2009)
This project analyzed the impact on the performance of a floating point Fast Fourier Transform (FFT) of modifying design parameters that included the number of points, precision, and folding factor. The performance parameters ...
High frequency behavioral modeling of second-order sigma delta modulators
(2006)
Sigma delta modulators (ΣΔMs) form part of the core of today’s mixed-signal de- signs. They are cornerstone components of oversampled data converters. Such data converters take advantage of digital signal processing ...
Analytical model development for lc parasitic estimation in power electronics circuits
(2010)
Technology trends in Power Electronics (PE) design continue to move toward board size reduction and increasing operating frequencies. However, as board sizes are reduced and operating frequencies increased, Electromagnetic ...
Design of an automated wafer-level parametric test for measuring the reverse recovery parameters of ldmos devices
