MN86063
High-Speed CODEC LSI for Facsimile Images
Overview
The MN86063 is a high-speed LSI codec for compressing and decompressing facsimile images. Features include real-time printing to laser printers, built-in line memory, enlargement and reduction, and code conversion.
Function
Message coding: MH, MR, MMR, and MG3. The chip also supports data transfers on the image and system buses and DMA transfers on the image bus alone. Coding conversion The chip converts between all supported message coding systems: MH, MR, MMR, and MG3. Enlargement/reduction These may be added to coding, decoding, code conversion, and data transfer operations. (1) In the primary scan direction, the chip uses multiplication on the change point address.
