  • System for handling multiple discrete cosine transform modes and method thereof
    Publication number: 20030133619
    Abstract: A system and methods are described for processing image data related to both 8-8 image data, corresponding to a single 8×8 image data set, and 2-4-8 image data, corresponding to two related 4×8 image data sets associated with different fields of an 8×8 image block. The image data is received and processed using separate discrete cosine transform (DCT) matrices. An 8-8 matrix processes the 8-8 image data and a 2-4-8 matrix processes the 2-4-8 image data. The matrices are used to generate forward DCT results when accessed in a normal fashion. The matrices are transposed through a column-major accessing scheme to generate inverse DCT results.
