LC8213K
Image Data Compression/Expansion Processor
Preliminary
Overview
The LC8213K compresses and expands the binary image
data used in fax and similar applications and can be used
in office automation equipment such as G3 or G4
facsimile systems, image filing systems, digital copiers,
and engineering workstations. The LC8213K supports
encoding methods that conform to the MH (Modified
Huffman), MR (Modified relative element address
designate), and MMR (Modified MR) encoding
techniques as stipulated in the ITU-T T.4 and T.6
recommendations.
Features
• Conforms to the ITU-T T.4 and T.6 MH, MR, and
MMR encoding methods.
• Supports G3 and G4 facsimile.
• Handles up to 64k bits in the main scan direction.
• Line skip mode
• 8/16-bit image memory bus, 8-bit CPU bus
• Supports data transfers between the CPU bus and the
image memory bus.
• DMA transfer function for data transfers between image
memory and I/O devices
• Executes encoding processing and DMA transfers
simultaneously
• System clock frequency: Up to 25 MHz
• CMOS structure supporting low power dissipation
