Overview
The MN86062 is a high-speed LSI codec for compressing and decompressing images using the MH, MR, and MMR standard compression methods specified in the ITU-T T.4 and T.6 recommendation. Registers and other settings provide flexible support for a variety of processing.

FEATUREs
• Compression methods MH, MR, and MMR
• Operating mode: Page mode
• Bus configuration: Choice of dual- or single-bus operation
• Decoding error processing: Choice of replacing with the previous line or a white line
• Image bus configuration: 8 bits, maximum 16 megabytes address space of image bus, 2-channel master DMA
• System bus configuration: X80 interface compatible, 8 bits, 2-channel slave DMA
• Pixels per line: maximum 64K, in byte increments
• Concurrent DMA transfers over image bus and command processing
• Support for pointer management for image buffer
• Wide selection of independent parameters for coding, decoding, transfers between buses, and DMA transfersr
• Support for time-shared processing by line for both coding and decoding
