摘要： The graphics data processor of the present invention offers as a single instruction in its instruction set a draw and advance operation. A first data register stores a set of X and Y coordinates. In a first embodiment, a predetermined color code is stored at the pixel address of a bit mapped display memory indicated by the X and Y coordinates the first data register upon execution of the the draw and advance instruction. The X and Y coordinates stored in the first data register are then advanced by addition of X and Y coordinates stored in a second data register. A second embodiment is similar except that the color code stored at the X and Y coordinates of the first date register is recalled for combining with the predetermined color code and the combined result stored at that pixel location. The predetermined color code is preferrably stored in another data register. By proper selection of the X and Y coordinate data stored in the second data register either the X or the Y coordinate may be altered alone or both may by simultaneously changed. Provision of signed X and Y coordinate values in the second register enables either the X or Y coordinate to be incremented of decremented. This instruction serves to inhance the speed at which a line or computed curve may by drawn in the bit mapped display.

摘要： The graphics processing apparatus of the present invention utilizes individual registers of a register file to store the X and Y coordinates of pixels. These X and Y coordinates though formed into a single data word are separable by, for example, having the most significant bits specifying the Y coordinate and the least significant bits specifying the Y coordinate. The graphics processing apparatus supports instructions which provide separate and independent data manipulation of these X and Y coordinates. These X Y coordinate manipulation instructions can provide for separate X Y arithmetic operations on two data words, separate X and Y compare operations, separate X and Y data move operations and a conversion between the X Y address form to the linear address form. This technique is highly useful for manipulation of X Y address coordinates in a visual display system employing bit mapped graphics.

摘要： The present invention presents a process of moving an array of pixel data representing an image to be displayed from a source memory space to a destination memory space. The array of pixel data is arranged in words containing a plurality of individual pixel datum. The process includes transforming each pixel datum in the word fetched from the source memory space to a colorized pixel datum by individually attaching color information to each pixel datum. The transforming occurs substantially in parallel on all of the pixel data in each word. This technique permits storage of commonly used images such as alphanumeric characters of various fonts or icons in a compressed form with one bit per pixel. These images are formed in color using the color expand operation at the time of drawing into the color display memory. Otherwise these images would need to be stored in multiple bit per pixel color form for all desired colors requiring considerable memory for redundant data. This color expanded image may then be combined with the color image stored in a selected part of the display memory and the combined image stored in that selected part of the display memory. Thus monochrome images may be expanded into color images and then combined with color images already in the display in a single operation.
摘要翻译： 本发明提出了将表示要从源存储器空间显示的图像的像素数据的阵列移动到目的地存储空间的处理。 像素数据阵列以包含多个单独像素数据的单词排列。 该过程包括通过将颜色信息单独地附加到每个像素数据来将从源存储器空间获取的单词中的每个像素数据变换为彩色像素数据。 变换基本上平行地发生在每个单词中的所有像素数据上。 这种技术允许以每个像素一位的压缩形式存储常用图像，例如各种字体或图标的字母数字字符。 这些图像在绘制到彩色显示存储器时使用颜色展开操作形成为彩色。 否则，这些图像将需要以多个位的每像素颜色形式存储，以便所有需要大量存储器的冗余数据。 然后，该彩色扩展图像可以与存储在显示存储器的选定部分中的彩色图像和存储在显示存储器的该选定部分中的组合图像组合。 因此，单色图像可以扩展成彩色图像，然后在单一操作中与已经在显示器中的彩色图像组合。

摘要： The graphics data processing apparatus which can logically combine the color data for two image arrays on a pixel by pixel basis, according to a nonlinear saturating function. Two examples of such functions are addition with saturation at the maximum value and subtraction with saturation at the minimum value. These functions can be employed to obtain computer graphics effects not feasible using other function, such as simulating spray painting and light mixing.

摘要： The present invention is a graphics data processor which includes the capability of determining whether a defined pixel location in a graphics display is within a window in an X Y coordinate system. The respective X and Y coordinates of the selected pixel are separately compared with the window limits. The window limits are preferable expressed as the X and Y coordinates of two diagonally opposite vertexes of a rectangular window. The results of this comparison are preferable available in two forms. In a first embodiment a single data processing instruction enables the generation of a digital data word which indicates the relation of the pixel to the window. This digital word includes a separate indication of the relationship of the pixel to the vertical and horizontal window limits. This indication can be used to generate a "trivial rejection" in determining whether a line or line segment passes through the window by ANDing the results for two points on the line. In a second embodiment the window compare capability is employed to determine whether or not a destination pixel is within the window. This is useful in array move instructions in which an entire array of pixels is moved to a location in the display. The array move may be aborted if a window violation is found or the move may be modified to plot to the display only those pixels within the window. This capability enables saving a great deal of time in graphics applications in which windows are employed by reducing the overhead needed for window determinations.
