Abstract: PowerPC controller has powerful communication capacity, stability, and compatibility. Therefore, it has been found extensive applications in test systems and communication fields. Designing PowerPC controller is based on PXI Express standard, which complies COM Express schema. For 8-slice-memory structure of controller, a detailed analysis of signal integrity design of DDR2 SDRAM is given, the routing structure of 8 branch topology with optimal timing is realized, and its effectiveness with post-routing timing simulation is verified. The PowerPC controller has abundant interfaces, which realizes communications between system controller and peripheral devices flexibly, and achieves expected design objective.
