摘要： A cursor display control in a graphic display system is provided in which a storage range is provided for exclusive use for a cursor pattern and a desired shape is defined in the storage range to thereby perform a high-speed cursor movement. A display control apparatus in the graphic display system includes a memory (510, 520) for storing a cursor pattern, shift register (530) for performing a shift processing in a non-display period of the cursor for positioning in the display screen, and parallel-serial converter (101, 103) for performing parallel to serial conversion at the display timing of the cursor, whereby the apparatus is suitable to be integrated in the form of an LSI and the cursor can be moved at a high speed on the screen.

摘要： A microprocessor suitable for processing a large quantity of graphics data. Graphics processing apparatus and method using the microprocessor are also disclosed.
The microprocessor (1) independent of a CPU has two ports (102, 103), and performs an instruction fetch and a data access or a memory access simultaneously to two memories (3, 10; 3, 4, 10) coupled through separate buses.
In the graphics processing apparatus in which this microprocessor is employed, the graphics transfer between a system memory (10) and a frame memory (4) can be performed at higher speed.摘要翻译： 适合于处理的图形数据的大量的微处理器。 使用微处理器的图形处理装置和方法是如此游离缺失盘。 的CPU的微处理器（1）独立的具有两个端口（102，103）中，在指令执行获取和数据访问或同时的存储器访问两个存储器（3，10; 3，4，10）耦合以通过独立的总线 ， 在其中采用该微处理器的图形处理装置，系统存储器（10）和一个帧存储器（4）之间的图形转印可以在更高的速度进行。

摘要： A graphic processing system has a processor - (10) for managing a display area and a character font area which are disposed in the same address space (14). From coded information indicative of a character transferred through a data bus of the system, the processor calculates an address at which a character font pattern of the corresponding character has been stored and transfers that character font pattern to a predetermined position on the display area. The graphic processing system realizes high speed development of fonts.

摘要： Disclosed is a font pattern processor (GDP) including font pattern storing means (FPT1) for defining a font pattern and font pattern access parameter storing means (FDR) for storing parameters for making access to this font pattern storing means (FPT1). Address calculation is made on the basis of the font pattern access parameter and a pattern code supplied from outside to indicate a font pattern. The font pattern processor (GDP) can include pattern drawing attribute indicating means (FAR) for indicating the attributes of pattern drawing by the font pattern data thus read out. Thus, the present invention can process predetermined font data at a high speed inside it on the basis of the pattern code and can easily accomplish diversification of font patterns. Furthermore, the invention can improve freedom of pattern drawing on the basis of a predetermined original font pattern.
