摘要： A rendering processor having a plurality of DDA control circuits such that in each DDA circuit, the coordinates of source and destination images and gradation values are computed. Depending on the computation result, source and destination data to the raster arithmetic unit are generated so as to control the raster arithmetic unit, which enables a plurality of pixels to be generated and to be written in the memory during a memory access.

摘要： A graphic processing apparatus for generating, displaying or printing characters and graphic data. A successive column access is used in which a row address is designated for access to a memory and data in different column addresses within the designated same row address are successively accessed and buffer means for buffering a series of data between an access by a processor and an access to a memory is provided. A program and image information for display are stored in a main memory. A frame buffer and the main memory are integrally configured simply and small in size.

摘要： A graphic display processing system is disclosed, in which a two-dimensional pattern or an image of a three-dimensional pattern can be displayed on the display screen of a display device, and moreover it can be rapidly judged whether or not each graphic data on a display list formed in a graphic data buffer corresponds to a pattern in a pattern pick region (namely, pick aperture) set on the display screen. In more detail, display color data in the pick aperture is first read out of a frame memory for storing image data. In a case where an image of a three-dimensional pattern is displayed, depth values in the pick aperture are read out of a Z-buffer for storing depth values with respect to a displayed pattern. Next, the read-out display color data is compared with display color commands on the display list, or the read-out depth values are compared with depth values obtained from geometrical form commands on the display list, to check whether or not each graphic data on the display list indicates the same display color or depth value as that of a pattern to be picked, thereby selecting only graphic data which is judged to indicate the same display color or depth value as that of the to-be-picked pattern. Then, it is checked whether or not the selected graphic data indicates a pattern intersecting with the pick aperture. Thus, desired graphic data can be rapidly picked out of the display list.
