FPGA-Powered Embedded Vector Graphics

Another kind of graphic adapter architecture is presented in that paper. The essential features are the absence of obvious video memory and alternative structure of the logic design, which is generally combinatorial. The graphic adapter is designed for programmable FPGA devices and their specific logic resources. A video time-base, which is one of the main logic components, generates the periodic sequence of X-Y screen coordinates. These coordinates then pass to several combinatorial logics, which produce the brightness/color information of the light beam. Thus the combinatorial logic is used for modulation of the video signal.
