    Abstract: An apparatus and a method for character and graphics pattern generation in a bit mapped graphics display system that includes a pixel data manager (14) for supplying character bit maps and graphics patterns to a visible display memory (22). A character information memory (24) is utilized for the storage of character descriptive information which includes an address table (26), macro-instructions (28), (30), and (32) and character bit maps (34), (36) and (38). Each character in a set of characters has an associated macro-instruction and character bit map. The address table contains memory addresses that point to the macro-instructions. Each macro-instruction contains executable instructions that establish the size and location of a corresponding character bit map. To supply a character to the visible display memory, the pixel data manager fetches and executes a corresponding macro-instruction. Overhead burden on the central processing unit is minimized.

    Abstract: Appareil et procédé pour la création de caractères et de modèles graphiques dans un système d'affichage graphique en mode point, comportant un gestionnaire de données de pixels (14) pour fournir des modèles graphiques et des cartes de bits de caractères à une mémoire d'affichage visible (22). On utilise une mémoire d'information de caractères (24) pour le stockage d'informations relatives à la description des caractères, qui comporte une table d'adreses (26), des macro-instructions (28, 30 et 32), ainsi que des cartes de bits de caractères (34), (36) et (38). Chaque caractère dans une série de caractères possède une carte de bits de caractères et une macro-instruction associées. La table d'adresses contient des adresses de mémoire désignant les macro-instructions. Chaque macro-instruction comporte des instructions exécutables établissant la taille et l'emplacement d'une carte de bits de caractères correspondante. Afin de fournir un caractère à la mémoire d'affichage visible, le gestionnaire de données de pixels appelle et exécute une macro-instruction correspondante. On minimise ainsi le fardeau de servitude sur l'unité centrale.

    Abstract translation: 用于在位图图形显示系统中创建图形字符和图案的设备和方法,包括像素数据管理器(14),用于将图形模板和字符的位图提供给存储器 可见显示器(22)。 字符信息存储器(24)用于存储与字符描述有关的信息,该信息包括地址表(26),宏指令(28,30和32)和 (34),(36)和(38)的位图。 一系列字符中的每个字符都有一个关联的字符位图和宏指令。 地址表包含指定宏指令的存储器地址。 每个宏指令包含建立相应字符位图的大小和位置的可执行指令。 为了向可见显示存储器提供字符,像素数据管理器调用并执行相应的宏指令。 这可以最大限度地减少中央单元的劳动负担。
