Raster-scan/calligraphic combined display system for high speed processing of flight simulation data

Claim 1

In a raster-scan/calligraphic combined display system for high speed processing of flight simulation data, the combination comprising: (a) geometric calculator means for determining projected geometric positions of scene features to be displayed; (b) memory means for storing image data and accessable directly by said geometric calculator means; (c) WRITE ADDRESS buffer circuit means for supplying an address to said image data; (d) input data bus means for connecting said image data from said geometric calculator means to said WRITE ADDRESS buffer circuit means; (e) scanline data memory means connected to said input data bus means to hold, for each surface to be displayed, the details of each raster scanline representing such surface; (f) surface pointer memory means connected to said input data bus means for holding a START ADDRESS in each scanline for such surface; (g) a plurality of processor means to process said image data to build up a set of intensity values for successive scanlines of a display; (h) said plurality of processor means connected in parallel for receiving, in rotation, one scanline of data; (i) buffer means connected with each of said processor means for receiving and storing temporarily data defining the intensity value of a plurality of pixels within a scanline; and (j) pixel processor means for writing said intensity values into locations in said buffer means corresponding to said image data.
