Explanation
Industry Standard Architecture - Student Guide 1 - Page 37 AMD processors are able to communicate with each other through HyperTransport point-to-point links. This enables one processor to access the memory connected to another processor. Inside the processor, a crossbar switch connects the processor, memory controller, and HyperTransport links. AMD processors also use HyperTransport links to connect to the I/O subsystem. The links on particular processors are connected to I/O tunnels that support the I/O devices. All other processors can communicate with the I/O system through the HyperTransport links. Legacy devices are also connected to one of the I/O tunnels.
