1. A system on chip (SOC), comprising:
an intellectual property (IP) core; and
a bus;
wherein the IP core is configured to:
obtain, based on an access address corresponding to an access command, an address range configuration identifier corresponding to the access address; and
transmit the access command and the address range configuration identifier to the bus; and
wherein the bus is configured to route the access command to a system cache (SC) or an external memory based on the address range configuration identifier, wherein a first path of the bus is connected to the SC, and a second path of the bus is connected to a controller for routing to the external memory.
