USB、串口、并口是PC機和外設(shè)進行通訊的常用接口，但對于數(shù)據(jù)量大的圖像來說，若利用串行RS-232協(xié)議進行數(shù)據(jù)采集，速度不能達(dá)到圖像數(shù)據(jù)采集所需的要求；而用USB進行數(shù)據(jù)采集，雖能滿足所需速度，但要求外設(shè)必須支持USB協(xié)議，而USB協(xié)議與常用工程軟件的接口還不普及，給使用帶來困難。有些用戶為了利用標(biāo)準(zhǔn)并行口(SPP)進行數(shù)據(jù)采集，但SPP協(xié)議的150kb/s傳輸率對于圖像數(shù)據(jù)采集，同樣顯得太低。因此,為了采集數(shù)據(jù)量大的圖像數(shù)據(jù),本文采用了具有較高傳輸速率的增強型并行口協(xié)議(EPP)和FPGA，實現(xiàn)對OV
