This core can perform the two dimensional Discrete Cosine Transform (DCT) and its inverse (IDCT) on an 8x8 block of samples. The simple, fully synchronous design allows for fast operation while maintaining a low gate count. It offers high performance and many features to meet your multimedia, digital video and digital printing applications
