<p>In a device for controlling the displaying of characters for a video system, the memory for storing information relating to the displaying of the characters is partitioned into two areas: a first area (Z1, Z1') for storing, at fixed addresses, data and parameters for general control of the display; and a second area (Z2) which is divisable into spaces (B1, B2, B3) of variable sizes so as to store, in each of the spaces, control parameters and data relating to the displaying of a row of characters, the spaces being chained together by virtue of a parameter, the address of the next memory space, stored in each space. This memory architecture offers multiple possibilities for modifying the display parameters from one row to another within one and the same "screen" whilst optimizing the size of the memory used. <IMAGE></p> |
