摘 要：“實時視頻采集及預處理系統”其主要目的是：實時采集標準PAL制視頻，并且對采集到的無壓縮的視頻信息進行預處理，然后將處理后的有用信息傳送軟件系統進行高級處理。由于本系統采集視頻數據的數據傳輸率高達40MB/s，所以必須采用當今主流的PCI總線與PC相連。
 本設計主要是將噪聲信號產生器產生的信號、存儲、經PCI接口送入主機供應用軟件使用，在本次設計中用一個白噪聲信號發生器來模擬產生圖象的數字信號。
 
 關鍵詞：PCI局部總線操作，PCI局部總線

Design of PCI Interface

 Abstract:The system of real time video frequency collection and pretreatment is the subsystem of the system with 3D laser colorful scanning. Its first objective is to collect the standard PAL video frequency with real time, and to pre-process the video frequency without being compressed, then to send the useful information after processing to the software system that processes this information. Because the data bit in this system is as high as 40M/S, we have to use the PCI Bus that is prevailing now to connect with PC.
 This design is the noise signal creation machine creation signal and save and was connected by PCI primarily arithmetic figure signal that a people sends into the host supply uses the software usage, imitating to produce the portrait in the convenient a noise signal in this design occurrence machine.
