Pattern generation display system |
摘要 |
A pattern generation display system has a pattern code processing means, a refresh memory, a pattern generator and a pattern data processor. A pattern position on the raster scan display is defined by a base position datum and a displacement datum. The pattern code processor can calculate both of the position data as the address data for an effective operation. The refresh memory stores the code of a pattern and the displacement datum thereof at the address corresponding to the base position datum thereof. The pattern data processor completes the display of the pattern at the position deviated from the base position by the displacement datum. Such a system can easily shift the pattern generated by the pattern generator on the display screen by a small pitch. Therefore, it is easy to adjust the position of characters corresponding to the character or sentence features.
