ABSTRACT:
A data processing apparatus for image display includes a character generator, a bit map type image memory, a CPU for accessing the character generator and the image memory to control the data stored in the image memory, a display, and a display controller for reading out the data stored in the image memory in accordance with a command from the CPU and supplying the readout data to the display. The image display apparatus further includes an image memory controller having a barrel shifter for parallelly shifting the data supplied from the CPU by a designated number of bits, a mask controller for outputting a mask data to restrict a write range of the data supplied from the CPU and a write controller for operatively combining the data from the barrel shifter and the data read from the image memory in accordance with the mask data to prepare a write data and supplying the write data to the image memory.
