An image display control system stores display data in a memory. A display coordinate generator generates coordinates on a display space, based on a count for use in position control of display scan. An address generator generates addresses of the display data stored in the memory, based on the coordinates generated by the display coordinate generator. A memory interface device accesses the memory according to the addresses generated by the address generator. Mode-setting registers set a display mode for each memory access slot required for accessing one address of the memory. A slot-selecting device selects a set value from set values stored in the mode-setting registers to indicate the display mode. A decoder decodes the set value selected by the slot-selecting device to generate a control signal corresponding to the display mode to be supplied to the address generator and the memory interface device. A delay device delays the control signal generated by the decoder by a time period required by the address generator for generating each of the addresses generated by the address generator.
