摘要： PROBLEM TO BE SOLVED: To improve the execution efficiency of a parallel plotting processor by reducing the overhead caused by the overlapped transfer of the same data and further decreasing the transfer amount by improving the compressibility of invalid data at a device for performing display processing by transferring a plotting data stream from a main processor to plural plotting processors enabling parallel processing. SOLUTION: A main processor 1 is provided with a means 3 for grouping data, group identification information is added to the data stream, and concerning the data stream in the same group, data are constituted without overlapping. The invalid data are converted into the same invalid value and compressed. The data stream of the same group is distributed by a distributing means 12 so as to be processed at the same plotting processor and at respective plotting processors 15 and 16, calculating processing is performed while referring to information transferred in the past as well.

摘要： A method of drawing figures for a multi-window system in which a plurality of window regions are set on a display screen, and in which a window which is partly overlapped on other windows and is partly concealed is controlled by being divided into a plurality of display or non-display subregions, and the displayed content is changed by designating the window. If a dot constituting the figure is generated from a dot generator, coordinate values of the dot are compared with position data of the designated window to select a dot located in the window. The selected dot is compared with position data of a subregion that constitutes the designated window to find a particular subregion in which the dot exists. If the particular subregion is a display region, the dot located therein is produced on the display screen. A dot generated next is compared with the particular subregion and is determined to be displayed or not. When the dot lies outside the particular subregion, the region to be compared to the dot position data is changed, and the dot position is compared with another subregion or with the designated window.

摘要： PURPOSE: To display the processed result of a plotting instruction on a screen in the same sequence as that in which the plotting instructions processed in plural threads in parallel and transferred by mixing are started up. CONSTITUTION: Plotting instruction streams consisting of the plotting instructions (instructions) provided with stream order information and plotting order information generated by the plural threads sequentially are transferred existing mixedly to a graphic bus controller(GBC) 19 by CPUs 11-12, and the GBC stores a received instruction in memory 20 sequentially, and generates a table to designate the plotting order of each instruction, and reads out the instruction in sequence of plotting by the table, and selects a processor which processes the instruction from processors 27-30 observing a load state, and sets its identifier as the first processor of the ID of the instruction, and sets the identifier of the processor which processes the next instruction as the second processor of the ID, and a raster converter 21 reads in and processes the instruction from the processor, and reads in the next plotting instruction from the processor of a second processor of the ID.

摘要： PURPOSE:To provide high-speed display performance by parallelly executing plotting for the unit of a command at a display system for receiving plural plotting commands. CONSTITUTION:When the plotting command for new plotting is received, '1' is added to the reception order number of plotting commands stored in a counter 205, this number is stored again, this new reception order number is added to the plotting command and distributed to a processor as depth information to be used for a Z buffer, at the time of plotting execution, the depth information added to the plotting command is compared with the depth information already written in the Z buffer 109 for each dot on the display screen and only when the depth information added to the plotting command is larger, the new depth information is written in the Z buffer 109 and plotted into a display memory 108. Since the Z buffer 109 is used, plotting can be parallelly executed regardless of the limitation of a plotting order.

摘要： PURPOSE:To prevent the incorrectness of display due to overtaking by executing plotting commands whose plotting ranges do not overlap or the plotting commands whose poltting ranges overlap but which are of the same color in parallel by each processor. CONSTITUTION:A computer main body 101, display terminal equipment 102, CPUs 104, 105, a main storage device 106, a display storage device 107 and a bus 103 are provided. Then, in the case that the plotting commands with sepentiality are inputted successively to a display device provided with plural processors, the plotting range of the plotting command inputted successively is calculated, and besides, the plotting color is extracted out of the plotting command, and the plotting range and the plotting color of the command being plotted are compared with each other processor for the calculated plotting range and the extracted plotting color, and as the result of that comparison, the plotting commands whose plotting ranges do not overlap or the plotting commands whose plotting ranges overlap but which are of the same color, are executed in parallel in each processor.

摘要： PURPOSE:To realize the working of a program under a multi-application environment of a screen by detecting a program requesting a display output without setting a display area and executing this request after converting it into a display area setting request and a display request given into the display area. CONSTITUTION:An output request issued to a display 7 from a user program is analyzed and a program which is trying to perform display is detected without setting any display area on a screen 71. Then a display area is allocated and the request is converted for execution of the display. Thus the request is carried out. A requester program, a display area identifier, and a correspondence table of positions and sizes on a screen are added and replaced every time the display area is requested in order to detect a program which is trying to display the information without securing a display area on the screen 71. Then it is checked whether the relevant program is included in said correspondence table or not for each display request. If not, it is regarded that the program is detected. Thus it is possible to carry out even a program assuming application of an entire screen together with a program assuming the multiple application of the screen.

摘要： PURPOSE:To simultaneously generate a document which has mixed a character and a graphic on one page, by outputting a graphic display frame being similar to the second area on an output document from an output means corresponding to the first area, onto a screen, when a command for starting a graphic processing is inputted. CONSTITUTION:As for a rectangular area (a text data is edited automatically so as not to be placed in this area) which has cleared a frame in order to place a graphic, a length/width ratio of the area goes different in accordance with a line interval and a character interval of the text data, at the time of printing, therefore, by taking notice of this face, at the time of plotting a graphic, a frame of a size being proportional to a frame size at the time when it is printed actually is supplied to a user as an area for plotting a graphic. The user makes a graphic data on a CRT display screen so that a print image can be monitored on the screen. In such a way, the same graphic generating frame as an actual output shape of an output device side is displayed on the display screen, therefore, the user can obtain a document having the same graphic as a graphic monitored in this frame, and an operation for generating a document is improved remarkably.

摘要： PURPOSE:To write images and characters and patterns turned into images simultaneously at plural points on a frame memory by using a divided frame memory operating mechanism which divides a frame memory into plural sections and can operate these section independently of each other. CONSTITUTION:The characters 102 or a pattern 103 written on a frame memory 101 are divided into plural sections and divided frame memory operating mechanisms 404-406 which can be operated independently of each other are correspond to those divided sections. Thus the images or characters or patterns turned into images can be written simultaneously on the memory 101. Furthermore the time needed to write those images on the memory 101 can be shortened when characters or patterns are displayed on a bit map type display device.
