2. Outline of functions
The electronic sort system compresses, expands, or rotates image
data sent from the digital copier to convert them into serial data and
sends them back to the digital copier.
(1) Host interface
The host interface is composed of the image data I/O interface and
the CPU interface.
The image data interface is composed of the data reception section
which received data frame the host and the video data output section which outputs print data.
The CPU interface is available in two kinds: the serial interface
which performs command communication with the host and the I/O
port interface.
CPU
(3) Rotation process
In rotation process, image data are transmitted to the page
memory according to the specified rotation mode (0, 90, 180, 270).
As the rotation process buffer, work memory of 512 kbit is used.
(4) Page memory (DRAM)
The page memory capacity is 24 Mbyte.
The page memory stores image data from the host. When outputting video data, reading is performed with the output timing of video
signals.
When writing into the page memory, rotation function, and 2 in 1/4
in 1 function are performed.
DRAM (24MB)

M66236
Sync clock
generation
(2) Coding/decoding process
In coding process, image data from the host interface is coded by
QM-coder (M65762) and stored in the compression memory.
In decoding process, coded data in the compression memory are
decoded by QM-coder and transmitted to the gate array.
(5) Video output data process
Video data are sent to the host with the data output clock (Video)
in synchronization with the horizontal sync signal (/HSYNC).
The horizontal sync signal and Video clock are synchronized by
M66236.
When outputting video data, the left margin function, the solid line
frame function, and the center erase function process are performed at the same time.
