Full-Optional Board Configuration and Outline of Image Data Flow
From scanner
Optional-configuration image flow
1. While the data from the scanner is read into the shared memory, the data is distributed
to the EDR and CRT reduction board.
2. After the completion of the reading, the data is temporarily saved to the HDD, and one
frame is freed for the next image acquisition.
3. After the write to the HDD is completed, the shared memory is used for double buffer,
so that a portion of the image is loaded in the shared memory.
4. While handshaking with the shared memory, optional image processing is performed
for output to the LP.
5. As with step 3 above, the data for network output is loaded from the HDD into the
shared memory.
6. If rotation is required, the loopback path of BUSCON is used to implement rotation.
The result of processing requires one screen worth of frame.
7. While handshaking with the shared memory, compression is performed.
8. Compressed blocks are sequentially saved to the HDD.
9. Once the process described in step 8 is completed for one frame, the data is read on a
block-by-block basis for transfer to the LAN board. If distributed processing is provided
(FINP), the data is block-transferred from the HDD to the shared memory for each
distribution destination.
10. For each distribution destination, the image is transferred from the shared memory on
a block-by-block basis and sent to the LAN.
