PCIE system

Hi there
As I know in normal PCIE system, we have CPU, root complex and Switch ... and end point is PCIE. Let say in PC main-board, I can think "root complex" is look like "North Chipset" . Am I right?
So now in FPGA, if you want to build a system that have PCIE IP core, then what to think about "root complex" here? It use to make transaction between CPU and Switch, which connect to "end point" is PCIE IP core.
thanks a lot
