摘　　要：外设部件互连标准(PCI)是目前个人电脑中使用最为广泛的接口,其位宽为32位或64位,工作频率为33 MHz,最大数据传输率为133 MB/s(32位)和266 MB/s(64位)。PCI-E是PCI最新的发展方向,其具有串行、点对点传输,每个传输通道独享带宽、支持双向传输模式和数据分通道传输模式等特点;在PCI-E 3.0规范中,X32端口的双向速率高达320 Gbps,可以满足新一代的I/O接口需求。Peripheral component interconnect(PCI)is the most widely used interface in the current personal computer,and its bid width is with a 32-bit or 64-bit width,operating frequency is 33 MHz and maximum data transfer rate is 133 MB/s(32-bit)and 266 MB/s(64-bit).PCI-E is the latest development direction of PCI,it has the characteristics of serial,point-to-point transmission,and each transmission channel has exclusive bandwidth,and it supports two-way transmission mode and data channel transmission mode.In the PCI-E 3.0 specification,the bidirectional rate of X32 port is up to 320 Gbps,which can meet the requirements of the new generation of I/O interfaces.
