Abstract:
A display screen with a plurality of display lines contains a storage (34) that receives lateral offset values for each line to be displayed. When the corresponding line is to be displayed, the offset value is transferred from the storage (34) to an offset register (22), whose outputs control a multiplexer (26) to select an appropriately delayed output tap of a shift register, containing the signals to be displayed.

Abstract:
PURPOSE:To load the large quantity of screen attribute data by reading the screen attribute data during a horizontal display period, setting them in a register with the use of a DMA function, and preventing character data from being displayed during the horizontal display period. CONSTITUTION:A bus controller 15 accesses a DMA row starting address in a row table area by a row table address signal in the last horizontal fly-back interval during a horizontal scanning fly-back interval. According to an accessed DMA row starting address, a DMA row in a display data area 9 is read in the horizontal display interval continuously after the horizontal fly-back interval. The screen attribute data on the read DMA row are supplied to the buffer of the controller 15, and supplied to a DMA controller 17 of a display controller 16 by a prescribed timing signal. The controller 17 DMA-transfered the set data and pallet data out of the supplied data respectively to an I/O register 18 and to the memory of a pallet mechanism 19.
Abstract:
A method for displaying images in each of plural adjacent areas on a display screen (10) having a plurality of display rows uses stored boundary data to freely define a boundary between adjacent areas in row direction and to switch the image display upon crossing the boundary. In a system for implementing the method, the images to be displayed are stored in an image information storage (20), which is addressed by start addresses contained in a row information storage (40; 50) to read out the information of various images to be displayed in each display row. A boundary information storage (30) contains the boundary data for each display row, which data is loaded into a boundary indication means (60) that controls an address generation means (70) for the image information storage to switch the start address received from the row information storage (40; 50) to a new image when a boundary is crossed.
