SoC Transaction Router
The SoC Transaction Router is a central hub that routes transactions between the CPU
cores, graphics controller, IO and the memory controller. In general, it handles:
cores, graphics controller, IO and the memory controller. In general, it handles:
•
CPU Core Interface: Requests for CPU Core-initiated memory and IO read and write
operations and processor-initiated message-signaled interrupt transactions
operations and processor-initiated message-signaled interrupt transactions
•
Device MMIO and PCI configuration routing
•
Buffering and memory arbitration
•
PCI Config and MMIO accesses to host device (0/0/0)
