摘要
A vector generator for us with an all-points-addressable frame buffer capable of the non-word aligned access, simultaneously, of a square M by N array of pixels providing fast vector drawing independently of vector slope and position in the whole screen area of an attached display monitor. The vector generator utilizes a triangular logic matrix together with a line drawing unit to generate M vector bits lying in an M by N square matrix of the screen of an attached monitor in one memory cycle of the frame buffer and uses the generated matrix to generate a direct mask for the frame buffer whereby the M bit vector may be stored in a single memory cycle.
