Overview
HD63085---------------- DICEP(Document Image Compression and Expansion Processor) The HD63085 (DICEP) is a LSI that compresses (or encodes) and expands (or decodes) the digital data representing a docu· ment image.
The DICEP uses Modified Huffman (MH) coding scheme, Modified Relative Element Address Designate (MR) coding scheme and Modified MR (M'R) coding scheme which are compatible with the CCITT (Comite Consultatif Interna· tional Telegraphique et TeJephonique) recommendations for Group 3 and Group 4 facsimile apparatus.
As the DICEP stores coding and decoding algorithms in the microprogram ROM as firmare, a single MPU command allows this LSI to encode or decode a scan line of digital ...
