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.
