CPU Complex Architecture
The CPU complex in the CPX8216 contains two CPU modules and their
corresponding Hot Swap Controller (HSC) modules. The figure below
illustrates the architecture, including elements on the boards as well as
local connections between the CPU modules and the PCI-to-PCI (P2P)
connections to the local CompactPCI buses.
