PROCESSING UNIT
(MCPU) - A2
BOARD
The BOOT CODE of the MCPU BOARD A2:
• provides configuration information for the MICROCONTROLLER
and checks the memory.
• checks the main application program on the PCMCIA CARD
under the MCPU BOARD A2 and loads it into the main memory
of the MCPU BOARD A2.
• starts the application program for the CR 825/850 SYSTEM.
• checks that the MCPU BOARD A2 signals can be sent between
the MSC BOARD and the INTERNAL PC.
• reads the calibration data stored on the PCMCIA CARD.
• checks the DIGITIZER BOARD A3 using a diagnostic program on
the DIGITIZER BOARD A3.
The MCPU BOARD A2:
• obtains raw image data from the DIGITIZER BOARD A3
• changes the image data from 16-bit linear to 12-bit log data
• actuates the LASER
• provides correction of the Collector Profile for the image data
• sends the image to the INTERNAL PC for image processing and
viewing
• provides the DIGITIZER BOARD A3 and the GALVO BOARD A4
with the scanning parameters determined by the size of the
SCREEN to be scanned
• records the maximum pixel value of a scan to allow the "smart
erase" algorithm can calculate the time to erase the SCREEN
• provides an interface to the MSC BOARD A1
