Estimating the term…
A graphics display system includes a host processor calculating graphic data and providing the graphic data to a graphics processor, and frame memories which store the graphic pixel data and supply display data to display devices. The graphics display system also includes a first register group which stores the graphics data, a second register group which converts and/or stores the data in the first register group, a pixel generator which generates pixels according to the graphic data in the second register group, and a plotter which writes the pixel data generated in the pixel generator in the frame memories. The second register group fetches the data from the first register group when the host processor issues a command for plotting, holds the data previously written by the host processor. At the same time, when the host processor issues a command for plotting, the specified graphic type is written in the graphic processor as well as data calculated based on the first and second register groups.
A graphics display system comprising multiple graphic processors assigned for each pixel stored in an image memory so as to respectively generate straight lines in parallel, said graphics display system further comprising
A CAD system comprising a plurality of graphic processors, an image memory storing pixels therein divided into pixel groups in an array based on the number of processors in said plurality, one of said graphic processors assigned to each of said pixel groups, each graphic processor selecting, from the pixel groups assigned to that graphic processor, pixels for a straight line connecting given start and end points, said CAD system further comprising
A system comprising multiple graphic processors used to plot a straight line by parallel processing with said multiple graphic processors executing Bresenham's algorithm, said system further comprising:
