DICEP(Document Image pression and
Expansion Processor)
The HD63085 (DICEP) is a LSI that presses (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 patible with the CCITT (ite Consultatif Interna- tional Telegraphique et TeJephonique) remendations 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 mand allows this LSI to encode or decode a scan line of...
