This paper examines the architecture, algorithm and implementation of a switch-based multi-processor realization of the fast Fourier transform (FFT). The architecture employs M pr...
We present algorithms for the type-IV discrete cosine transform (DCT-IV) and discrete sine transform (DST-IV), as well as for the modified discrete cosine transform (MDCT) and it...
This paper describes the optimisation of the word length in a 16-point radix-4 reconfigurable pipelined Fast Fourier Transform (FFT) based receiver device. Two forms of optimisati...
In this paper we propose a framework for gradient descent
image alignment in the Fourier domain. Specifically,
we propose an extension to the classical Lucas & Kanade
(LK) a...
Short vector SIMD instructions on recent microprocessors, such as SSE on Pentium III and 4, speed up code but are a major challenge to software developers. We present a compiler t...
