Abstract: A system on chip, an access command routing method, and a terminal are disclosed. The system on chip includes an IP core and a bus. 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, where the address range configuration identifier is used by the bus to route the access command. The bus is configured to route the access command to a system cache or an external memory based on the address range configuration identifier.
