本文對(duì)基于PCI 總線的數(shù)據(jù)采集系統(tǒng)硬件及軟件設(shè)計(jì)作了詳細(xì)的說明，設(shè)計(jì)出的數(shù)據(jù)
采集系統(tǒng)可以應(yīng)用于諸如數(shù)字示波器、數(shù)字頻譜儀和語音識(shí)別等領(lǐng)域。系統(tǒng)采用了PCI 總線作為數(shù)據(jù)采集系統(tǒng)的支持總線，以TMS320C5402DSP 作為板載CPU，實(shí)現(xiàn)了數(shù)據(jù)的高速實(shí)時(shí)傳輸與處理。另外設(shè)計(jì)采用WinDriver 設(shè)計(jì)驅(qū)動(dòng)程序，不但縮短了驅(qū)動(dòng)程序的開發(fā)周期，而且方便了硬件調(diào)試，取得了良好的效果。

Abstract: The thesis explains the DSP data collecting card based on PCI bus and software design in detail .The data collecting card can be applied to the fields such as digital oscillograph, digital spectral appearance and phonetic recognition etc. The high speed transmission and real-time processing of the data is realized through adopting PCI bus and TMS320C5402 DSP in this system. The good result is based on the shortening of development period and convenient hardware debugging while I design driver with the WinDriver.
