ABSTRACT:
A display control system for a scan type display apparatus in which a display screen is divided into a plurality of split display regions on a video screen and each display region is scanned in parallel. A dual port memory having a random access port and a serial access port is used as a display memory and display data is inputted through the random access port and outputted through the serial access port. Display addresses for reading out sequentially display data corresponding to each raster of every split display region one by one from the dual port memory are generated and the display data of each of the split display regions read out from the dual port memory are stored into each of the buffer memories. The display data stored in the buffer memories is read out and transferred to the scan type display device.
