Pre-processing Speech Signals in FPGAs
Jun Xu, A. M. Ariyaeeinia, Reza Sotudeh, Zainal Arifin Ahmad · 2006
Algorithms are traditionally developed on off-the-shelf digital signal processors. Recent silicon technology advance has made FPGAs feasible as an alternative solution. However, most of signal processing work in the past has been focused on implementing on software, which has led to a wide gap between algorithms and hardware. This paper is aimed to explore algorithm hardware-migration technologies, in particular, speech signal pre-processing algorithms into FPGAs.
