Abstract: ?Many technologies and devices are based on peripheral component interconnect (PCI). Because of interface technology and other reasons, there is no large area transition to peripheral component interconnect express (PCIE). Therefore, it is necessary to research PCIE-to-PCI data conversion technology. In order to carry out high-speed data conversion of PCIE-to-PCI bus more conveniently and efficiently, PCIE-to-PCI circuit system based on PI7C9X130 is designed, the hardware design scheme and test method are introduced in detail. The experiment shows that the working mode of the downstream PCI card slot can be changed under the condition that the PCB can work normally, and the transmission time and packet loss rate are less than 10 ms and 5×10^-4 after stable operation for at least 30 minutes. It verifies the feasibility and reliability of the design.
