also inserted together with this integrated circuit. 100Hz integrated circuit multiplies
50Hz LVDS data that it receives from main IC to 100Hz; also processes it through
MEMC (motion estimation and motion compensation) algorithms and sends the
picture to the panel as double LVDS output. In addition to previously mentioned
software and EEPROM files, 100Hz products have their own software. 100Hz
software is located in "Ursa" folder in the "Target" folder. This software is used by
MST7338P. For 100Hz integrated circuit, there is also 1 optional EEPROM location,
but it is not being used.

As explained above, RAM is the part that undertakes the processing load of actual
integrated circuit. To this end, 100Hz integrated circuit has to process constantly to
convert 50Hz video to 100Hz and while coding inter-frame with MEMC algorithm.
These processes are performed in RAM. Here again, RAM's supply voltage is
important as well as this voltage's not changing quickly.
