| Abstract: | A project is present based on FPGA for horizontal indicator in aircraft cockpit to improve the performance of the old project based on DSP+FPGA.Graphics are drawn,memory and LCD are controlled by FPGA while parameters are calculated by DSP.Less calculation was needed according to the symmetry of graphics and the graphics-drawing speed is improved by parallel processing and hardware implement.The refresh rate and resolution of the graphics are advanced with simply system organization. |
