Open publisher page 0 citations

Abstract

An algorithm to accurately identify the VGA mode is designed in this paper,which is based on the horizontal synchronous signal and the vertical synchronous signal,and can be applied to FPGA in order to complete the scheme of the VGA video collection card through the frequency counting theory.The algorithm is implemented in Verilog HDL,and is accomplished by Quartus II of the Altera company.
