 Title: On the Error-Free Computation of Fast Cosine Transform Authors: Dimitrov, VassilWahid, Khan Keywords: DCTImage CompressionAlgebraic IntegersError-Free Computation Issue Date: 2005 Publisher: Institute of Information Theories and Applications FOI ITHEA Abstract: We extend our previous work into error-free representations of transform basis functions by presenting a novel error-free encoding scheme for the fast implementation of a Linzer-Feig Fast Cosine Transform (FCT) and its inverse. We discuss an 8x8 L-F scaled Discrete Cosine Transform where the architecture uses a new algebraic integer quantization of the 1-D radix-8 DCT that allows the separable computation of a 2-D DCT without any intermediate number representation conversions. The resulting architecture is very regular and reduces latency by 50% compared to a previous error-free design, with virtually the same hardware cost.
