Low cost design of IFFT module for dolby AC-3 decoder

Abstract

Dolby AC-3 is a flexible audio data compression technology capable of encoding a range of audio channel formats into a low rate bit stream. AC-3 is the de facto audio standard for high-end digital consumer multimedia equipment. In this thesis work we have implemented 8 point FFT module using radix-2 algorithm. This work also shows the implementation of 128 point IFFT module using split radix algorithm.
