A generalized algorithm and reconfigurable architecture for efficient and scalable orthogonal approximation of dct

The document discusses a generalized recursive algorithm for orthogonal approximation of the discrete cosine transform (DCT) aimed at reducing computational complexity while maintaining coding performance. It highlights the limitations of existing algorithms, particularly in terms of non-orthogonality and small transform lengths, and presents a solution using sparse matrix decomposition and DCT basis vector symmetries. Additionally, the document includes various sections such as a literature survey, system analysis, implementation details, and contact information.
