1. An analog image data is output from CIS unit to IC500.
IC500 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400
and IC401 through DDR-SDRAM I/F.
2. CPU in IC300 compress the data in IC400 and IC401.
3. CPU in IC300 transfer the data to MODEM in IC300
and output it to TEL LINE through DAA (IC100 and IC101) circuit.

1.FAX data is input from TEL LINE to MODEM in IC300 through DAA
(IC100 and IC101) circuit. And then store it in IC400 and IC401 through
DDR SDRAM I/F.
2. CPU in IC300 decompress the data in IC400 and IC401.
3. PCI I/F in IC300 retrieve the data from IC400 and IC401 and output it to IC600.
And PCI I/F in IC600 retrieve the data from IC300 and store it to IC960 through
DDR SDRAM I/F.
4. Image processing in IC600 retrieve the the data from IC960.
Image processing does enlargement /reduction processing, dithering processing
and store the data in IC960.
5. C-wyle(*1) Encode in IC600 encode the data and store the data in IC960.
6. C-wyle Decode in IC600 decode the data and output it to Print I/F .
And Print I/F in IC600 retrieve the data from C-wyle Decode and output it to LSU.
