| Abstract: |
| In the proposed design scheme the CRTC is replaced by FPGA, and the method of producing timing signal of VGA using VHDL is given. Thereby the design scheme of VGA controller in the digital voice system based on FPGA is completed. The design is applied to the display in the digital voice system. |
| Key words: digital voice system display FPGA VHDL VGA |
