| Title: | A new convolution structure for the realisation of the discrete cosine transform | Authors: | Chan, YH Siu, WC |
Issue Date: | 1990 | Source: | 1990 IEEE International Symposium on Circuits and Systems : New Orleans, Louisiana, May 1-3, 1990, v. 3, p. 2373-2376 | Abstract: | In this paper, we present a new formulation for converting a length-N(=2[sup m]) Discrete Cosine Transform into two length-N/2 correlations. This formulation enables us to realise the Discrete Cosine Transform with a reduced number of operations compared to conventional approaches and it also results in extremely regular structure which is most suitable for the realisation using distributed arithmetic. | Keywords: | Correlation methods Digital arithmetic Transforms |
