Abstract
Video display control apparatus for a visual display device (11, Fig. 1, not shown) employing a television- type raster in a word processor has a display memory (13), a column counter 25 and a row counter 28 adapted to address the display memory. Each location of the display memory has an address comprising a column number and a row number. A clock oscillator (18) and a timing chain (19) produce raster timing signals and column and row timing signals. The count in the column counter 25 tracks the line being scanned, and the count in the row counter tracks successive groups of lines in the raster. The display data output of the display memory controls a character matrix memory (15) acting through a parallel-to-serial converter (16) to cause alphanumeric characters to be displayed in rows by the display device. So that the information display by the display device can be varied in a convenient manner, the row counter 28 is coupled to the display memory 13 through a random access memory 30 which stores information from a central processor unit (14). This stored information determines which set of sequential row addresses shall be supplied to the display memory as the row counter 28 carries out its counting sequence, and includes an instruction associated with a selected row address which causes a reset signal 31 to be supplied to the column counter 25 so that for this row the characters displayed start at the character stored in the first column of locations in the display memory, the column addresses generated by the column counter 25 being otherwise selectable as any set formed by a predetermined number of consecutive column addresses for alphanumeric character locations in the display memory. <IMAGE>
