A flexible chip set for intra frame video compression

LSI Logic has developed a two-chip processor for the core operations of the proposed JPEG (Joint Photographic Experts Group) image coding standard which is able to encode and decode all legal bitstreams and images regardless of compression rate. The user may thus be ensured that a legal bitstream is being generated regardless of image contents or compression ratio. The L64735 and L64745 have been designed to bridge the gap between building-block solutions and single-chip solutions for JPEG image coders. The two-chip approach offers some performance advantages over more highly integrated chips, as well as an assurance that all images regardless of their compression rate or contents can be safely handled at video rates.<>
