| Abstract: | Unlike traditional bus, the PCI Express Bus employs Point to Point interconnection, and every devices are connected by individual links, so that occupying their own bandwidth, increasing the transmission rate. PCIE switch or bridge can provide protocol transform capability and bring the interconnection in the system with convenient solution. This paper introduces a data processing module designed on PEX8648 switch chip for the interconnection of mltiple PCIE devices, and presents the hardware framework and software configuration in detail. |
