Abstract

PURPOSE: To optionally perform bit map processing for data displayed on a CRT screen by inputting display data to a dual-port RAM while sending them out to a CRT, and processing a bit map for the display data in this dual-port RAM. CONSTITUTION: When the display data outputted in synchronism with a synchronizing signal are sent out to the CRT 6 and displayed, the display data are inputted to the dual-port RAM 9 at the same time. Therefore, the bit map of one screen displayed on the CRT 6 is exploded on the dual-port RAM 9. Then character data in bit map form are processed by a host or dedicated CRT controller 7 as required through a dual-port RAM controller 8. The processed display data are sent out of the dual-port RAM 9 to the CRT 6 according to display timing to make a display according to the display data after the bit-map processing. Consequently, the data displayed on the CRT screen can optionally be processed into the bit map.
