用FPGA实现数字语音系统中的VGA控制器

FPGA-based Design of the VGA Controller of a Digital Voice System

介绍了用FPGA代替显示器控制器(CRTC),并用VHDL产生VGA时序信号的详细方法,从而完成了用FPGA实现数字语音系统中的VGA控制器的设计方案。这种设计方法已经应用于数字语音系统的显示部分。

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.
