Discrete Cosine Transform, 2D Inverse (IDCT)
"The CAST IDCT coreimplements the 2D Inverse Discrete Cosine Transform on an 8x8 block of coefficients. Hence, it is appropriate for IDCT-based image or video decoders and can be used as a core for JPEG, MPEG1, MPEG2, MPEG4, H.261, and H.263 standards. It is based on the row-column computational architecture. The design is fully synchronous with positive-edge clocking and no internal tri-state buffers. It offers high performance while maintaining a low gate count and can be used in any multimedia, digital video, and digital printing applications.
